This report is submitted pursuant to a contract dated August 30, 1967, between the Iowa State Highway Commission and Howard, Needles, Tammen & Bergendoff, Consulting Engineers, in connection with studies determining (11,A) alternate pavement designs, and (11,B) criteria for geometric design studies. Included herein is that portion of the report covering Paragraph 11,A, comprising preparation of alternate type pavement designs (Portland Cement and Asphaltic Concrete) for the Cedar Valley Freeway and proposed US-518 from 1-80 to US-30. These alternate pavement designs consider quality and availability of aggregates, soil conditions and traffic information, to determine details and dimensions of pavement design. Comparative cost studies were prepared from alternate design data and recommendations as to pavement type are presented for Commission review.

O modelo de gestão estratégica do Ministério Público do Estado do Rio Grande do Norte: a análise da implantação do Balanced Scorecard

The goal of this research was to analyze the model of strategic management of the MPRN concerning the methodological guidelines presented by Balanced Scorecard. It is based in a theoretical referential which contemplates the themes, new public management, strategic management and Balanced Scorecard, focusing on applying the methodology in the public sector. This research is classified as descriptive and exploratory. According to the methods applied, it is a case study and, according to its approach, it is qualitative. The subjects of this research are members of the institution involved in the process of its strategic management. The data was collected by means of semi-structured interviews and document analysis, done by means of method content analysis. Concerning the goal of this research, it points out that the MPRN has not concluded the implantation cycle of Balanced Scorecard, furthermore, important flaws in the steps of organizational alingment have been identified, specially when it refers to communication policy, implementing incentive actions and focused training in developing competences. It yet reveals that the implantation of BSC has allowed the introduction of changes in the Institution dynamics to seek better results, however the MPRN has faced and has not adequately gotten over the same difficulties reported in various cases of BSC implantation in public organizations

L'échantillonnage équilibré par la méthode du cube et la méthode rejective

Au cours de ces dernières années, les techniques d’échantillonnage équilibré ont connu un regain d’intérêt. En effet, ces techniques permettent de reproduire la structure de la population dans des échantillons afin d’améliorer l’efficacité des estimations. La reproduction de cette structure est effectuée par l’introduction des contraintes aux plans de sondage. Encore récemment, des nouvelles procédures d’échantillonnage équilibré ont été proposées. Il s’agit notamment de la méthode du cube présentée par Deville et Tillé (2004) et de l’algorithme réjectif de Fuller (2009). Alors que la première est une méthode exacte de sélection, la seconde est une approche approximative qui admet une certaine tolérance dans la sélection. Alors, après une brève présentation de ces deux méthodes dans le cadre d’un inventaire de pêcheurs, nous comparons à l’aide de simulations Monte Carlo, les plans de sondage produits par ces deux méthodes. Aussi, cela a été l’occasion pour nous de vérifier si ces méthodes modifient les probabilités de sélection des unités.

Clinical trial designs of new medicinal products for treating schizophrenia: discussion of EMA's Guideline and a Better Long Term Trial Design

Background and Objectives: Schizophrenia is a severe chronic disease. Endpoint variables lack objectivity and the diagnostic criteria have evolved with time. In order to guide the development of new drugs, European Medicines Agency (EMA) issued a guideline on the clinical investigation of medicinal products for the treatment of schizophrenia. Methods: Authors reviewed and discussed the efficacy trial part of the Guideline. Results: The Guideline divides clinical efficacy trials into short-term trials and long-term trials. The short-term three-arm trial is recommended to replace the short-term two-arm active-controlled non-inferiority trial because the latter has sensitivity issues. The Guideline ultimately makes that three-arm trial a superiority trial. The Guideline discusses four types of long-term trial designs. The randomized withdrawal trial design has some disadvantages. Long-term two-arm active-controlled non-inferiority trial is not recommended due to the sensitivity issue. Extension of the short-term trial is only suitable for extension of the short-term two-arm active-controlled superiority trial. The Guideline suggests that a hybrid design of a randomized withdrawal trial incorporated into a long-term parallel trial might be optimal. However, such a design has some disadvantages and might be too complex to be carried out. Authors suggest instead a three-group long-term trial design, which could provide comparison between test drug and active comparator along with comparison between the test drug and placebo. This alternative could arguably be much easier to carry out compared with the hybrid design. Conclusions: The three-group long-term design merits further discussion and evaluation.

Towards balanced exploitation and management of the fishery resources of Uganda

A casual study of the hydrological map of Uganda would convince every serious fisherman and fisheater that he is most favoured to be in Uganda. The extent and distribution of the country's aquatic system plus the rich variety of fish species there is promises a fishery potential of considerable magnitude: The open waterways comprised by the Uganda portions of Lakes Victoria, Albert and Edward; and Lakes Kyoga, George plus minor lakes Wamala, Kijanebarora, mutanda, etc. occupy about 15% of the total surface area (91,000 m2; Depart. Land Survey, 1962). Most of the nation's fish supplies are currontly from this source. 1.2. A rich network of permanent and seasonal rivers and streams filling and/or emptying various water systems covers most of Uganda. This aquatic network is associated with a fish fauna whose immense significance as a source of protein is perhaps better appreciated by the local subsistance fisherman and consumer than by the fisheries scientist and manager in this country. Many species of this fish fauna have strong affinities with the open water systems while some are typically riverine. 1.3. Then there are wetlands composed mainly of expanses of swamp, but including some areas of bog. These cover about 2% of the country. While the variety of fish fauna found here is limited by the rather hostile nature of the environment (comparatively de-oxygenated under a canopy of dense stands of emergont vegetation) several specialised fishes e.g. Clarias spp. and Protpterus aethiopicus (Kamongo) occur here. Availability of permanent and seasonal sources of water, well distributed throughout most areas of Uganda, opens up immense potential for a variety of aquaculture practices. However, while active exploitation of much of these fishery resources is currently underway, important questions regarding the magnitudes of the various resource potentials and dynamics, and about suitable levels and modes of exploitation, are yet unanswered. These gaps in knowledge go about the fishery resources of Uganda would hinder formulation of adequate development and management schemes. This short paper examines some of the above problems and suggests some approaches towards balanced oxploitation and management of the fisheries of Uganda.

Exploiting Nested Parallelism on Heterogeneous Processors

Heterogeneous computing systems have become common in modern processor architectures. These systems, such as those released by AMD, Intel, and Nvidia, include both CPU and GPU cores on a single die available with reduced communication overhead compared to their discrete predecessors. Currently, discrete CPU/GPU systems are limited, requiring larger, regular, highly-parallel workloads to overcome the communication costs of the system. Without the traditional communication delay assumed between GPUs and CPUs, we believe non-traditional workloads could be targeted for GPU execution. Specifically, this thesis focuses on the execution model of nested parallel workloads on heterogeneous systems. We have designed a simulation flow which utilizes widely used CPU and GPU simulators to model heterogeneous computing architectures. We then applied this simulator to non-traditional GPU workloads using different execution models. We also have proposed a new execution model for nested parallelism allowing users to exploit these heterogeneous systems to reduce execution time.

Optimal Controller Designs for Rotating Machines - Penalising the Rate of Change of Control Forcing

In the context of active control of rotating machines, standard optimal controller methods enable a trade-off to be made between (weighted) mean-square vibrations and (weighted) mean-square currents injected into magnetic bearings. One shortcoming of such controllers is that no concern is devoted to the voltages required. In practice, the voltage available imposes a strict limitation on the maximum possible rate of change of control force (force slew rate). This paper removes the aforementioned existing shortcomings of traditional optimal control.
