Introduction:Today, many countries, regardless of developed or developing, are trying to promote decentralization. According to Manor, as his quoting of Nickson’s argument, decentralization stems from the necessity to strengthen local governments as proxy of civil society to fill the yawning gap between the state and civil society (Manor [1999]: 30). With the end to the Cold War following the collapse of the Soviet Union rendering the cause of the “leadership of the central government to counter communism” meaningless, Manor points out, it has become increasingly difficult to respond flexibly to changes in society under the centralized system. Then, what benefits can be expected from the effectuation of decentralization? Litvack-Ahmad-Bird cited the four points: attainment of allocative efficiency in the face of different local preferences for local public goods; improvement to government competitiveness; realization of good governance; and enhancement of the legitimacy and sustainability of heterogeneous national states (Litvack, Ahmad & Bird [1998]: 5). They all contribute to reducing the economic and social costs of a central government unable to respond to changes in society and enhancing the efficiency of state administration through the delegation of authority to local governments. Why did Indonesia have a go at decentralization? As Maryanov recognizes, reasons for the implementation of decentralization in Indonesia have never been explicitly presented (Maryanov [1958]: 17). But there was strong momentum toward building a democratic state in Indonesia at the time of independence, and as indicated by provisions of Article 18 of the 1945 Constitution, there was the tendency in Indonesia from the beginning to debate decentralization in association with democratization. That said debate about democratization was fairly abstract and the main points are to ease the tensions, quiet the complaints, satisfy the political forces and thus stabilize the process of government (Maryanov [1958]: 26-27). What triggered decentralization in Indonesia in earnest, of course, was the collapse of the Soeharto regime in May 1998. The Soeharto regime, regarded as the epitome of the centralization of power, became incapable of effectively dealing with problems in administration of the state and development administration. Besides, the post-Soeharto era of “reform (reformasi)” demanded the complete wipeout of the Soeharto image. In contraposition to the centralization of power was decentralization. The Soeharto regime that ruled Indonesia for 32 years was established in 1966 under the banner of “anti-communism.” The end of the Cold War structure in the late 1980s undermined the legitimate reason the centralization of power to counter communism claimed by the Soeharto regime. The factor for decentralization cited by Manor is applicable here. Decentralization can be interpreted to mean not only the reversal of the centralized system of government due to its inability to respond to changes in society, as Manor points out, but also the participation of local governments in the process of the nation state building through the more positive transfer of power (democratic decentralization) and in the coordinated pursuit with the central government for a new shape of the state. However, it is also true that a variety of problems are gushing out in the process of implementing decentralization in Indonesia. This paper discusses the relationship between decentralization and the formation of the nation state with the awareness of the problems and issues described above. Section 1 retraces the history of decentralization by examining laws and regulations for local administration and how they were actually implemented or not. Section 2 focuses on the relationships among the central government, local governments, foreign companies and other actors in the play over the distribution of profits from exploitation of natural resources, and examines the process of the ulterior motives of these actors and the amplification of mistrust spawning intense conflicts that, in extreme cases, grew into separation and independence movements. Section 3 considers the merits and demerits at this stage of decentralization implemented since 2001 and shed light on the significance of decentralization in terms of the nation state building. Finally, Section 4 attempts to review decentralization as the “opportunity to learn by doing” for the central and local governments in the process of the nation state building. In the context of decentralization in Indonesia, deconcentration (dekonsentrasi), decentralization (desentralisasi) and support assignments (tugas pembantuan; medebewind, a Dutch word, was used previously) are defined as follows. Dekonsentrasi means that when the central government puts a local office of its own, or an outpost agency, in charge of implementing its service without delegating the administrative authority over this particular service. The outpost agency carries out the services as instructed by the central government. A head of a local government, when acting for the central government, gets involved in the process of dekonsentrasi. Desentralisasi, meanwhile, occurs when the central government cedes the administrative authority over a particular service to local governments. Under desentralisasi, local governments can undertake the particular service at their own discretion, and the central government, after the delegation of authority, cannot interfere with how local governments handle that service. Tugas pembantuan occur when the central government makes local governments or villages, or local governments make villages, undertake a particular service. In this case, the central government, or local governments, provides funding, equipment and materials necessary, and officials of local governments and villages undertake the service under the supervision and guidance of the central or local governments. Tugas pembantuan are maintained until local governments and villages become capable of undertaking that particular service on their own.

This paper proposes a method for the identification of different partial discharges (PDs) sources through the analysis of a collection of PD signals acquired with a PD measurement system. This method, robust and sensitive enough to cope with noisy data and external interferences, combines the characterization of each signal from the collection, with a clustering procedure, the CLARA algorithm. Several features are proposed for the characterization of the signals, being the wavelet variances, the frequency estimated with the Prony method, and the energy, the most relevant for the performance of the clustering procedure. The result of the unsupervised classification is a set of clusters each containing those signals which are more similar to each other than to those in other clusters. The analysis of the classification results permits both the identification of different PD sources and the discrimination between original PD signals, reflections, noise and external interferences. The methods and graphical tools detailed in this paper have been coded and published as a contributed package of the R environment under a GNU/GPL license.

The need for the use of another surveillance system when radar cannot be used is the reason for the development of the Multilateration (MLT) Systems. However, there are many systems that operate in the L-Band (960-1215MHz) that could produce interference between systems. At airports, some interference has been detected between transmissions of MLT systems (1030MHz and 1090MHz) and Distance Measuring Equipment (DME) (960-1215MHz).

Office automation is one of the fields where the complexity related with technologies and working environments can be best shown. This is the starting point we have chosen to build up a theoretical model that shows us a scene quite different from the one traditionally considered. Through the development of the model, the levels of complexity associated with office automation and office environments have been identified, establishing a relationship between them. Thus, the model allows to state a general principle for sociotechnical design of office automation systems, comprising the ontological distinctions needed to properly evaluate each particular technology and its virtual contribution to office automation. From this fact comes the model's taxonomic ability to draw a global perspective of the state-of-art in office automation technologies.

This work focuses on the analysis of a structural element of MetOP-A satellite. Given the special interest in the influence of equipment installed on structural elements, the paper studies one of the lateral faces on which the Advanced SCATterometer (ASCAT) is installed. The work is oriented towards the modal characterization of the specimen, describing the experimental set-up and the application of results to the development of a Finite Element Method (FEM) model to study the vibro-acoustic response. For the high frequency range, characterized by a high modal density, a Statistical Energy Analysis (SEA) model is considered, and the FEM model is used when modal density is low. The methodology for developing the SEA model and a compound FEM and Boundary Element Method (BEM) model to provide continuity in the medium frequency range is presented, as well as the necessary updating, characterization and coupling between models required to achieve numerical models that match experimental results.

Damages -reduced in fruit packing lines is a major cause of grace reduction and quality loos in fresh marks: fruit. Fruit must be treated gently during in sir handling to improve their qualityin order to get a good price in a competitive market. The correct post-hardvest handling in fruit packing lines is a prerequisite to cut down the heavy post-harvest losses. Fruit packing lines must be evaluated, studying their design, the impacts applied to the fruits, the characteristics of the materials, etc. This study establishes the possibility of carrying out modifications and tests in a packing line during a long period of time. For this purpose, an experimental fruit packing line has been designed and located in the Agricultural Engineering Department of the Polythecnic University of Madrid with the aim of improving mechanical devices and fruit handling conditions to minimize damage to fruit. The experimental line consists of several transporting belts, one rollers transporter, one sizer, one elevator, one singularizer, and three trays to receive the calibrated fruit. The line has a length of 6.15 m and a width cf 1.9 m. Movement of the different components is regulated by electric motors with variable velocity electronically controlled. The height of the transfer points is variable and can be easily modified. The experimental line has been calibrated using two instrumented spheres IS 100 (8.8 cm Ø and6.2cm Ø). Average acceleration values obtained in all the transfers of the experimental line lay under 80 g's, although there is big variation for some of them being some values above 100 g's.

A system dedicated to the optical transmittance characterization of Fresnel lenses has been developed at NREL, in collaboration with the UPM. The system quantifies the optical efficiency of the lens by generating a performance map. The shape of the focused spot may also be analyzed to understand change in the lens performance. The primary instrument components (lasers and CCD detector) have been characterized to confirm their capability for performing optical transmittance measurements. Measurements performed on SoG and PMMA lenses subject to a variety of indoor conditions (e.g., UV and damp heat) identified differences in the optical efficiency of the evaluated lenses, demonstrating the ability of the Scanning Lens Instrument (SLI) to distinguish between the aged lenses.
