Day-ahead Resource Scheduling Including Demand Response for Electric Vehicles

The energy resource scheduling is becoming increasingly important, as the use of distributed resources is intensified and massive gridable vehicle (V2G) use is envisaged. This paper presents a methodology for day-ahead energy resource scheduling for smart grids considering the intensive use of distributed generation and V2G. The main focus is the comparison of different EV management approaches in the day-ahead energy resources management, namely uncontrolled charging, smart charging, V2G and Demand Response (DR) programs i n the V2G approach. Three different DR programs are designed and tested (trip reduce, shifting reduce and reduce+shifting). Othe r important contribution of the paper is the comparison between deterministic and computational intelligence techniques to reduce the execution time. The proposed scheduling is solved with a modified particle swarm optimization. Mixed integer non-linear programming is also used for comparison purposes. Full ac power flow calculation is included to allow taking into account the network constraints. A case study with a 33-bus distribution network and 2000 V2G resources is used to illustrate the performance of the proposed method.

A Communication and Resources Management Scheme to Support the Smart Grid Integration of Multiplayers Access to Resources Information

The increasing and intensive integration of distributed energy resources into distribution systems requires adequate methodologies to ensure a secure operation according to the smart grid paradigm. In this context, SCADA (Supervisory Control and Data Acquisition) systems are an essential infrastructure. This paper presents a conceptual design of a communication and resources management scheme based on an intelligent SCADA with a decentralized, flexible, and intelligent approach, adaptive to the context (context awareness). The methodology is used to support the energy resource management considering all the involved costs, power flows, and electricity prices leading to the network reconfiguration. The methodology also addresses the definition of the information access permissions of each player to each resource. The paper includes a 33-bus network used in a case study that considers an intensive use of distributed energy resources in five distinct implemented operation contexts.

Projeto de uma ETAR de 3200 habitantes equivalentes

A atividade humana e industrial usa a água para as suas atividades do quotidiano. A água é um recurso natural escasso cuja qualidade deve ser protegida, defendida, gerida e tratada em conformidade com o seu uso. Nesse âmbito, a gestão das águas prossegue objetivos de proteção da saúde humana e de preservação, proteção e melhoria da qualidade do ambiente[1]. Desde o final do seculo XIX até aos dias de hoje, verificou-se uma forte evolução nos sistemas de tratamento de águas residuais. Esta evolução foi fundamental para dar resposta às maiores exigências de qualidade do efluente tratado. O sistema de lamas ativadas é um dos processos de tratamento biológico das águas residuais mais usados em todo o mundo. Este trabalho consiste no desenvolvimento do projeto de conceção e dimensionamento de uma Estação de Tratamento de Águas Residuais (ETAR) para servir um pequeno aglomerado de cerca de 3200 habitantes equivalentes (hab.eq.), tendo como objetivo o dimensionamento de todas as etapas de tratamento necessárias ao cumprimento da legislação em vigor para a descarga das águas residuais urbanas no meio recetor. O Decreto-lei nº 152/97[2], relativo ao tratamento de águas residuais urbanas, juntamente com o Decreto-lei nº 149/2004[3] que identifica as zonas sensíveis e de zonas menos sensíveis, permitem que as entidades licenciadoras definam o grau de tratamento que a instalação deve possuir tendo em consideração a classificação do meio onde o efluente tratado é descarregado. O Decreto-Lei n.º 135/2009[1] estabelece o regime de identificação, gestão, monitorização e classificação da qualidade das águas balneares, impondo a qualidade microbiológica da água residual tratada mediante o meio recetor, e portanto conseguindo-se assim definir o tratamento de desinfeção a adotar. Resumidamente, a conceção do tratamento focou as seguintes etapas: tratamento preliminar formado por uma unidade compacta de tamisação, desarenador e desengordurador, tratamento secundário por lamas ativadas em regime de arejamento prolongado constituído por dois reatores com cerca de 400 m3 de volume seguido de um decantador com um diâmetro de 9.5 m, tratamento terciário de desinfeção composto por uma microtamisação seguido de desinfeção UV, e a utilização das operações comuns de espessamento e desidratação das lamas produzidas em excesso pelo tratamento, constituída por com um espessador gravítico com 4.6 m de diâmetro, e um filtro banda para a desidratação.

The importance of succession planning in family-owned Small and Medium Enterprises in Portugal

This work project addresses the importance of succession planning in family-owned Small and Medium Enterprises (SMEs). This is directly related with Human Resources Management (HRM) given that there is an HRM long term vision in order for the succession to be planned on time and benefit the companies. This study focused on SMEs since these are the entities that have a minor focus on HRM practices. A total of 22 in-depth interviews were conducted and analyzed. Selected SMEs owners/managers and successors/antecessors were interviewed with the purpose of acquiring more insight on the level of succession planning, using a qualitative methodology from which the process of succession was derived. This study unveils that the first step in this process is related to the definition of criteria to be a good successor, followed by the choice of possible successors, being the children the natural successors, but also considering other potential ones, and finally some considerations on the future of these companies.

Management of Cross Border Mergers and Acquisitions

This research thesis analyses the motivation behind the cross-border mergers and acquisitions deals. How mergers and acquisitions of new knowledge and assets, enhance business with expansion into new streams and international markets. Also, how mega deals help them to gain a power in the international markets. The research focuses on understanding the interrelation between motivations which are contributing to M&A activities and how issues like cultural differences and different management styles are overcome by these firms in cross-border settings. Chapter 1, gives a background knowledge on cross-border M&A as popular internationalization strategy choice, continuing with describing the process in Finnish and Japanese cultural context, and how these deals are proceeding in particular cases. Chapter 2, reviews the important findings and touches the common gaps or aspects those are not studied extensively, does play a key role in the success and failure of M&A deals. A methodology is presented in chapter 3, presenting the hurdles faced by many in this research field. Chapter 4, present the case study is presented to show how M&A can play an important role in structuring the entire economy of Japan. At last chapter 5, presents the evidence, if cultural, HRM and geographical aspects really contribute to the success of M&A, based on which managerial implications are suggested and propositions are built for future research references.

The Alberta Dilemma: Optimal Sharing of a Water Resource by an Agricultural and an Oil Sector

The purpose of this paper is to characterize the optimal time paths of production and water usage by an agricultural and an oil sector that have to share a limited water resource. We show that for any given water stock, if the oil stock is sufficiently large, it will become optimal to have a phase during which the agricultural sector is inactive. This may mean having an initial phase during which the two sectors are active, then a phase during which the water is reserved for the oil sector and the agricultural sector is inactive, followed by a phase during which both sectors are active again. The agricultural sector will always be active in the end as the oil stock is depleted and the demand for water from the oil sector decreases. In the case where agriculture is not constrained by the given natural inflow of water once there is no more oil, we show that oil extraction will always end with a phase during which oil production follows a pure Hotelling path, with the implicit price of oil net of extraction cost growing at the rate of interest. If the natural inflow of water does constitute a constraint for agriculture, then oil production never follows a pure Hotelling path, because its full marginal cost must always reflect not only the imputed rent on the finite oil stock, but also the positive opportunity cost of water.

De la gestion des ressources fauniques à la participation au processus d'évaluation environnementale : l'évolution d'un droit constitutionnel chez les Cris de la Baie James

Les Cris de la Baie James sont parmi les premiers bénéficiaires d'un traité moderne qui prévoit un rôle déterminant pour les Autochtones dans la gestion de l'environnement et du développement des ressources naturelles. À travers la Convention de la Baie James et du Nord québécois, les Cris participent à la gestion de l'environnement et sont assurés d'un droit de regard sur les projets de développement futurs dans l'ensemble de leur partie du territoire conventionné. Cette participation, qui est le fruit d'une intense négociation, est aujourd'hui renforcée, à travers des ententes de coopération subséquentes, grâce notamment, à l'émergence du mouvement écologiste qui a contribué à la reconnaissance d'un rôle particulier pour les Autochtones à l'égard de l'environnement. Par l'examen des mécanismes de protection de l'environnement, notamment le processus d'évaluation environnementale, aux termes du chapitre 22 de la Convention de la Baie James et du Nord québécois, cette étude met en lumière l'importance du processus de négociation et des droits qui en résultent par rapport à ceux reconnus en vertu de la doctrine des droits ancestraux telle que développée récemment par les tribunaux canadiens.

Le développement durable et l’Amazonie brésilienne : la régulation publique est-elle suffisante?

Combiner le respect du milieu et le bien-être des personnes qui vivent de l’exploitation des ressources naturelles en Amazonie est une préoccupation qui est appelée à transformer les politiques d’exploitation du territoire. Je montre dans cette étude que les gains du développement économique, la protection de l’environnement et l’amélioration du niveau de vie des populations locales sont des objectifs compatibles. Toutefois, des tensions entre les trois piliers du développement durable subsistent et nécessitent une forme de négociation pour arriver à un équilibre des coûts et bénéfices du développement. En Amazonie, cette négociation prend la forme d’un encadrement du développement par les législations gouvernementales. Ces lois clarifient les droits de propriété et établissent un système de gestion de l’exploitation des ressources forestières tant sur les terres publiques que sur les terres privées. En analysant deux cas d’exploitation de ressources issues de la forêt, soit le bois d’œuvre et la baie d’açaí, j’explique les raisons pour lesquelles les populations locales vivant de l’exploitation des diverses ressources forestières sont peu intégrées dans le processus de développement. La régulation publique s’appliquant à l’exploitation du bois tend à criminaliser les activités pratiquées par les populations locales sans apporter d’alternative autre que les plans de gestion forestière. Dans le cas de la baie d’açaí, la coexistence de la culture et de la cueillette comme systèmes de production permet aux populations locales de continuer leurs activités traditionnelles et une répartition des coûts et bénéfices du développement plus équitable entre les acteurs.

Poverty, Inequality and Natural Resources Degradation

The present study is an attempt to understand the link between natural resource degradation and poverty among people dependent on these resources. This is done by examining the impact of depletion of marine resources on the livelihood and socio-economic condition of the small-scale marine fishery community in South Kerala. In Kerala, nearly ten lakh fisherfolk depend on the marine fishery resources for their livelihood. The overall level of education of the small-scale fishing community is lower than that of the State’s rural population. Almost all the households surveyed, is one way or other, depend on fishery resources for livelihood. Low levels percapita income and high levels of inequality imply the existence of a large proportion of poor people in the community who are vulnerable to external shocks. The study reveals that poverty was comparatively higher among households with no fishing assets, with only one earner, with more than two children, and depending entirely on pensions/remittances. The study has not provided any evidence to show that poverty in the community is the result of depletion of marine resources.

Innovative Human Resource Practices and Selected HR Outcomes in Software Firms in Kerala

In this study the relationship between Innovative HR practices and selected HR outcomes is investigated.The current study represents a unique attempt to study the effects of innovative HR practices,with job satisfaction,organisational commitment and organisational citizenship bahaviour considered as the consequent variables.Results have affirmed the role of intervening variables such as job satisfaction and organisational commitment in establishing the link between IHRP and OCB obliterating any direct relation between IHRP and organisational citizenship behaviour.This finding may enable researchers in the human resource management to develop more robust understandings of the positive effects of innnovative HR practices on HR outcomes.Thus the present study provides the obvious contribution of weaving up yet another linkage between the two complimentary disciplines of Human Resource Management and Organisational Behaviour.The present study also contributes to the understanding of OCB by exploring its antecedents and extending the intervening role of job satisfaction and organisational commitment.The findings indicate that a higher level of introduction/initiation and satisfaction of innovative HR practices produces high job satisfaction and organisational commitment which lead to OCB.The researcher drew upon the perception-attitude-behaviour model to further realise the expected relationship among innovative HR practices,job satisfaction,organisational commitment and organisational citizenship behaviour.Consequently,this study makes a contribution to the broader organisational citizenship behaviour literature by manifesting the extended relationship path from innovative HR practices to organisational citizenship behaviour,and demonstrating that innovative Hr practices at the organisational level has an effect on employee attitudes and behaviours as well.

Heterotrophic bacteria from the continental slope sediments of arabian sea

The marine environment is indubitably the largest contiguous habitat on Earth. Because of its vast volume and area, the influence of the world ocean on global climate is profound and plays an important role in human welfare and destiny. The marine environment encompasses several habitats, from the sea surface layer down through the bulk water column, which extends >10,000 meters depth, and further down to the habitats on and under the sea floor. Compared to surface habitats, which have relatively high kinetic energy, deep-ocean circulation is very sluggish. By comparison, life in the deep sea is characterized by a relatively constant physical and chemical environment. Deep water occupying the world ocean basin is a potential natural resource based on its properties such as low temperature, high pressure and relatively unexplored properties. So, a judicious assessment of the marine resources and its management are essential to ensure sustainable development of the country’s ocean resources. Marine sediments are complex environments that are affected by both physiological and biological factors, water movements and burrowing animals. They encompass a large extent of aggregates falling from the surface waters. In aquatic ecosystems, the flux of organic matter to the bottom sediments depend on primary productivity at the ocean surface and water depth. Over 50% of the earth’s surface is covered by deep-sea sediments that are primarily formed through the continual deposition of particles from the productive pelagic waters (Vetriani et al., 1999). These aggregates are regarded as ‘hot spots’ of microbial activity in the ocean (Simon et al., 2002). This represents a good nutritional substrate for heterotrophic bacteria and favours bacterial growth

Studies On The Dynamics And Water Quality Of The Muvattupuzha River In Relation To Effluent Discharge

The present study aims at the investigation of the 1ysico—chemical features of a tropical tidal river viz. we Muvattupuzha river. This river is expected to receive Jderate to heavy pollution loads in years to come, from we lone industrial unit, already set up on its bank. ilike other rivers, the geographical disposition of this Lver attains unique importance as regards its dynamics for 3) availability of natural runoff water from catchment :eas, which becomes very heavy during the monsoon season 3) regular steady availability of tail race water from a /dro—electric power station throughout the yearThe study also aims at arriving at the balancing forces of inherent self~purification of the river verses pollution loads from the factory effluents. The investigation period falls ahead of actual pollution occurrence and so the ambient conditions for a period of nearly one-and-a—half years were investigated, the analyses of which providflz to formulate the inter-relations of parameters varying with seasons. Tracer experiments were carried out which revealed the dispersion and dilution characteristics of the river in the vicinity of effluent outfall. The studv covers the trial—cum-capacity production periods of the factory during which effluents of various strength and quantity were discharged into the river; a few computed values arQ’cjmpgrQdl ... with the observed values. The base data along with the profiles of Oxygen sag equation have been utilized fb develop a mathematical model of the river with regard to its water quality

Institutional Analysis of Marine Fisheries Management Practices in Kerala, India

The study is important for the fact that it places the management dynamics of marine fisheries sector in the context of growing unrest of local communities over the emerging resource conflicts and degradation Economic crisis in small scale marine fisheries due to high operating cost continue to hinder the efforts towards conservation in many ways The migration of mechanized fleet as a response to profit maximization strategy of enterprises continues to be a threat to resource management Therefore this study explores how to revamp the small scale mechanized sector effectively and profitably to ensure rational allocation of resources The thesis attempts to examine how livelihood vulnerabilities of artisanal fish workers influence the crafting of management institutions Finally by combining insights of an institutional framework the study establishes the need for recognising the role of both formal and informal institutions in the management of marine fisheries in Kerala

Climate-Adaptive Community Water Management for Food Security: Experiences from the UNDP Community Water Initiative

Facing the double menace of climate change threats and water crisis, poor communities have now encountered ever more severe challenges in ensuring agricultural productivity and food security. Communities hence have to manage these challenges by adopting a comprehensive approach that not only enhances water resource management, but also adapts agricultural activities to climate variability. Implemented by the Global Environment Facility’s Small Grants Programme, the Community Water Initiative (CWI) has adopted a distinctive approach to support demand-driven, innovative, low cost and community-based water resource management for food security. Experiences from CWI showed that a comprehensive, locally adapted approach that integrates water resources management, poverty reduction, climate adaptation and community empowerment provides a good model for sustainable development in poor rural areas.

Lightweight monitoring of label switched paths for bandwidth management

The purpose of resource management is the efficient and effective use of network resources, for instance bandwidth. In this article, a connection oriented network scenario is considered, where a certain amount of bandwidth is reserved for each label switch path (LSP), which is a logical path, in a MPLS or GMPLS environment. Assuming there is also some kind of admission control (explicit or implicit), these environments typically provide quality of service (QoS) guarantees. It could happen that some LSPs become busy, thus rejecting connections, while other LSPs may be under-utilised. We propose a distributed lightweight monitoring technique, based on threshold values, the objective of which is to detect congestion when it occurs in an LSP and activate the corresponding alarm which will trigger a dynamic bandwidth reallocation mechanism
