ECO URBAN DESIGN Potensi dan Tantangan Perencanaan Kota-kota Indonesia Di Masa Mendatang
No full textUntuk memenuhi kebutuhan perumahan pemerintah terus mendorong pemilikan rumah khususnya bagi masyarakat menengah ke bawah. Secara teoritis pemilikan rumah diyakini memberikan banyak manfaat baik secara sosial, ekonomi maupun lingkungan. Pemilikan rumah membantu menstabilkan lingkungan ketetanggaan (neighborhood) dan memperkuat komunitas. Strategi ini juga menciptakan insentif bagi lingkungan dan individu yang penting untuk memelihara dan memperbaiki properti pribadi dan ruang publik. Namun pemilikan rumah ternyata tidak otomatis menghadirkan manfaat- manfaat program tersebut. Orientasi pengembangan rumah menengah ke bawah pada pencapaian target secara kuantitas daripada kualitas tampaknya ikut mempengaruhi kontribusi lingkungan perumahannya terhadap kualitas lingkungan perkotaan.
Dalam beberapa penelitian tingkat kepuasan terhadap kondisi lingkungan perumahan telah dijadikan indikator kualitas lingkungan. Rendahnya tingkat kepuasan tersebut jelas akan mempengaruhi pemanfaatan rumah-rumah milik keluarga menengah ke bawah. Banyaknya rumah yang dibiarkan kosong oleh pemiliknya tidak terlepas dari kualitas lingkungan perumahan yang dikembangkan. Fenomena permumahan kosong ini menjadi persoalan besar karena tujuan pemilikan rumah untuk menciptakan lingkungan hidup perkotaan yang sehat baik secara ekologis, ekonomi maupun sosial kurang tercapai. Salah satu faktor yang paling berpengaruh terhadap terciptanya lingkungan yang berkualitas adalah tersedianya prasarana dan utilitas lingkungan yang memadai untuk mendukung kegiatan produktif keluarga.
Paper ini bermaksud mengungkapkan karakteristik kualitas lingkungan perumahan sederhana bagi masyarakat menengah ke bawah. Dari analisis tingkat mikro terhadap data kuesioner yang dikumpulkan pada beberapa sampel perumahan menengah ke bawah di kota Bekasi diharapkan akan dapat diungkapkan tingkat kepuasannya terhadap kondisi lingkungan perumahannya. Melalui identifikasi permasalahan tersebut diharapkan dapat diturunkan strategi-strategi yang sesuai untuk meningkatkan kualitas lingkungan di perkotaan melalui pelibatan masyarakat khususnya pada perumahan menengah ke bawah
The Design and Implementation of a Key Performance Indicator Dashboard for KE-chain
No full textKE-works is a six years old company which aims to optimise the product development process in industrial applications. To accomplish this, KE-works deploys a web-application called KE-chain. KEchain is an engineering workflow management system with the objective to increase the efficiency of the product development process through better control, more efficient distribution, access and use of product-related information. Users have the possibility to set-up a project, manage the tasks belonging to this project, and control the workflow and information distribution. With KE-chain users are able to create structure in the heap of information that composes their product and, when used right, improve the process of their project development. One of the key elements in optimising the product development process is the monitoring of the available data to give users insight in the status of the project. Currently it is difficult to get a good overview of a project within KE-chain and it is not possible to see what tasks are cirtical at a certain moment. A common way of showing the status or performance of systems is the use of Key Performance Indicators (KPI’s). These indicators, for example in the form of a graph or a table, can quickly give information about the performance of a system. KE-works has decided that it wants to give its users an overview in the formof a project-specific dashboard with KPI widgets. Therefore the assignment is to design and develop an integrated KPI dashboard into KE-chain. To design the KPI dashboard, which we named KE-board, we shortly researched the field of Performance Measurement to get an overview of the different approaches for the design of KPI’s. As a basis for the design we have adopted the Lean methodology [1] which has been used by KE-works in the past. In our research we have actually connected the Lean wastes to measures in KE-chain. To do this, we have chosen a bottom-up approach, which means we started by identifying the available data, after which we extracted several groups of measures. We have interviewed several clients of KEworks, the users of KE-chain. From these interviews we deducted which groups of measures were important for which user roles. To verify which measures are of importance for these dashboards, we have questioned and interviewd the consultants of KE-works. By combining the results of the interviews and the questionnaires we designed 7 KPI widgets. Finally, we created KE-board and integrated it into KE-chain in five weeks of implementation. After that we have evaluated the complete dashboard by interviewing the consultants of KE-works. On top of that, we have sent them a questionnaire in which they rated the functionality of the widgets to see if they contribute to their purpose and achieve the goals that we set for them. KE-board has been received well by the management and employees of KE-works and according to the extensive evaluation we can state that it definitely contributes to the optimization of the product development process in KE-chain.Computer ScienceComputer ScienceElectrical Engineering, Mathematics and Computer Scienc
Computational identification and analysis of protein short linear motifs
No full textShort linear motifs (SLiMs) in proteins can act as targets for proteolytic cleavage, sites of post-translational modification, determinants of sub-cellular localization, and mediators of protein-protein interactions. Computational discovery of SLiMs involves assembling a group of proteins postulated to share a potential motif, masking out residues less likely to contain such a motif, down-weighting shared motifs arising through common evolutionary descent, and calculation of statistical probabilities allowing for the multiple testing of all possible motifs. Much of the challenge for motif discovery lies in the assembly and masking of datasets of proteins likely to share motifs, since the motifs are typically short (between 3 and 10 amino acids in length), so that potential signals can be easily swamped by the noise of stochastically recurring motifs. Focusing on disordered regions of proteins, where SLiMs are predominantly found, and masking out non-conserved residues can reduce the level of noise but more work is required to improve the quality of high-throughput experimental datasets (e.g. of physical protein interactions) as input for computational discovery
Optimal upper bound for the infinity norm of eigenvectors of random matrices
No full textLet be a random Hermitian (or symmetric) matrix whose upper diagonal and diagonal entries are independent random variables with mean zero and variance one. It is well known that the empirical spectral distribution (ESD) converges in probability to the semicircle law supported on . In this thesis we study the local convergence of ESD to the semicircle law. One main result is that if the entries of are bounded, then the semicircle law holds on intervals of scale . As a consequence, we obtain the delocalization result for the eigenvectors, i.e., the upper bound for the infinity norm of unit eigenvectors corresponding to eigenvalues in the bulk of spectrum, is . The bound is the same as the infinity norm of a vector chosen uniformly on the unit sphere in . We also study the local version of Marchenko-Pastur law for random covariance matrices and obtain the optimal upper bound for the infinity norm of singular vectors. This is joint work with V. Vu. In the last chapter, we discuss the delocalization properties for the adjacency matrices of ErdH{o}s-R'{e}nyi random graph. This is part of some earlier results joint with L. Tran and V. Vu.Ph.

Development of zein-based ice nucleator films for frozen food applications
No full textThis research aimed at developing zein-based ice nucleation films for the applications of frozen foods. Acetic acid was chosen as the solvent to cast zein films with flawless surface. Tributyl citrate (TBC) was mixed into zein films to various proportions and 10% TBC was most effective on improving mechanical properties resulting in 2.3-fold more flexibility and 5.8-fold more toughness compared to unplasticized zein films. But incorporation of 20% TBC significantly decreased the water absorption by 19% compared to 10% TBC. Thus, zein films with 20% TBC with good flexibility and water resistance was used in following experiments. The activity of ECINs was stable at pH between 4.0 and 9.0 and ionic strength between 0.01 M and 0.10 M. In the development of INFs, the optimum adsorption of ECINs on zein films surface occurred through layer-by-layer method at pH 7.0 and ionic strength of 0.05 M on UV/ozone-treated zein. A novel method was developed to quantify the activity of INFs, which revealed that the highest activity of zein-based INFs reached 175 units/mm2. The zein-based ice nucleation films (INFs) were used to wrap frozen bread dough during five freeze/thaw cycles. The high-activity INF was as effective as blending ECINs in improving the yeast survival by 40%, and consequently increased the specific volume of bread loaf by 25%. Furthermore, high-activity INFs prevented the dehydration of frozen dough and thus significantly reduced the crumb hardness by 36% and increased the crumb springiness by 1.25 times. On energy saving, zein-based INFs were less potential than blended ECINs. INFs only reduced the time of freezing by 6% compared to the 20% by blended ECINs. However, the total amount of ECINs used on wrapping a piece of dough was only about 1/200 of the amount through blending. In addition, ECINs immobilized on the zein films showed desirable stability to sustain at least fifteen repetitive uses on freezing water.Ph.

Integrating centralized and decentralized approaches for multi-robot coordination
No full textAutonomous multi-robot systems play important roles in many areas such as industrial applications for repetitive tasks, explorations in hazardous environments, and military missions in extreme conditions. Many existing coordination strategies are developed for two general types of multi-robot systems including strongly centralized systems and completely decentralized systems. For strongly centralized systems, the global information including the environment as well as the locations of all the robots is shared. It is typical for small number of robots in well structural environments and is not robust to dynamic environment or failures in communications and other uncertainties. For completely decentralized systems, each robot is executing its own control schemes completely autonomously. There are no specified leaders throughout the mission, and the team organization does not have a set structure. In many real-world applications, it is beneficial to use so-called weakly centralized systems, in which the leader robot is not specified a priori, but it is selected dynamically during the mission to guide the robot team through dynamic environments or other uncertainties. It is very challenging to develop coordination strategies for this type of systems because of the dynamic nature of the team structures. The strategies should not only allow for on-line leader role selection but also enable formation decomposition and reconfiguration whenever necessary. In this thesis, we describe a general coordination framework for weakly centralized multi-robot systems that integrates the features from both strongly centralized and completely decentralized coordination strategies at the individual robot level. The framework allows the robots to reconfigure the formation dynamically in the presence of obstacles or other uncertainties in the environment, and promotes the main advantages of multi-robot systems such as flexibility and modularity. Since the control schemes can be decentralized and this framework allows for the selection of the motion planner and local controller for a given task, the framework can be naturally applied to multi-robot systems with larger scales. We have implemented this framework on a team of two-wheeled differential driven mobile robots. Significant results from numerical simulations and experiments have been obtained to demonstrate that the coordination schemes are effective and robust, and the framework is viable and can be scaled to relative large scale multi-robot systems.Ph.D.Includes bibliographical referencesIncludes vitaby Ke X

Comparative measures of internal migration
No full textRigorous cross-national comparisons call for clearly defined, robust and reliable metrics. The IMAGE Project defined and implemented a suite of such metrics to make global comparisons on several dimensions of migration. This chapter reviews the impediments to such comparisons and development of the comparative metrics. It then sets out the way in which these statistical indicators are calculated for the three key dimensions of migration explored in this book: migration intensity, age composition and spatial impact. We describe the rationale for each measure, set out the relevant equations and illustrate their implementation. We also provide a brief synopsis of the IMAGE Studio, a software suite designed to compute both global and local indicators and address the Modifiable Areal Unit Problem (MAUP), a key impediment to spatial analysis. The chapter provides an essential reference for the material presented in the country-specific chapters which follow, while also offering a concise stand-alone guide to the IMAGE metrics
