PENGEMBANGAN MODEL PERKIRAAN PENUMPANG SAUM SEBAGAI DAMPAK PENGGUNAAN LAHAN PADA KAWASAN BERBASIS TRANSIT (STUDI KASUS: LRT KORIDOR III KOTA BANDUNG)

Transit-Oriented Development (TOD) merupakan konsep pengembangan kawasan perkotaan yang kerap diadopsi di Indonesia untuk mendukung penggunaan transit, terutama di perkotaan besar yang sudah memiliki rencana pengembangan kereta api perkotaan, seperti Kota Bandung. Konsep ini mengedepankan integrasi guna lahan dan sistem angkutan massal sehingga bentuk guna lahan di sekitar simpul transit atau stasiun menjadi penting. Penelitian terdahulu menunjukkan bahwa variabel-variabel yang berhubungan dengan guna lahan memberikan pengaruh terhadap peningkatan fungsi transit. Mayoritas kawasan TOD dan sistem transit di Indonesia masih dalam tahap perencanaan, sehingga kinerja nyata TOD dalam mendukung penggunaan transit belum dapat dipastikan. Penelitian ini bertujuan untuk mengembangkan model prediksi dampak kinerja bentuk penggunaan dan pengembangan lahan pada area potensi TOD terhadap jumlah pengguna transportasi publik. Model ini diharapkan dapat menjadi referensi pengukuran keefektifan rencana TOD dalam konteks pembangkitan pengguna transportasi publik baru. Metode analisis yang digunakan dalam penelitian ini adalah regresi linier berganda. Berdasarkan hasilnya, beberapa hal perlu dipertimbangkan dalam pengembangan model, yaitu pemilihan variabel, penentuan sampel dan pemilihan metode analisis

Multi-objective Pareto front and particle swarm optimization algorithms for power dissipation reduction in microprocessors

The progress of microelectronics making possible higher integration densities, and a considerable development of on-board systems are currently undergoing, this growth comes up against a limiting factor of power dissipation. Higher power dissipation will cause an immediate spread of generated heat which causes thermal problems. Consequently, the system's total consumed energy will increase as the system temperature increase. High temperatures in microprocessors and large thermal energy of computer systems produce huge problems of system confidence, performance, and cooling expenses. Power consumed by processors are mainly due to the increase in number of cores and the clock frequency, which is dissipated in the form of heat and causes thermal challenges for chip designers. As the microprocessor’s performance has increased remarkably in Nano-meter technology, power dissipation is becoming non-negligible. To solve this problem, this article addresses power dissipation reduction issues for high performance processors using multi-objective Pareto front (PF), and particle swarm optimization (PSO) algorithms to achieve power dissipation as a prior computation that reduces the real delay of a target microprocessor unit. Simulation is verified the conceptual fundamentals and optimization of joint body and supply voltages (Vth-VDD) which showing satisfactory findings

The interweaving of diaries and lives : diary-keeping behaviour in a diary-interview study of international students’ employability management

This article explores ‘diary-keeping behaviour’, or the ways in which participants conduct the completion and submission of diaries in diary research. There is a paucity of methodologically oriented literature on diary method and as such this article makes a contribution to extending the existing knowledge of this method. The primary aim of this article is to set out in detail the key issues relating to diary-keeping behaviour, in order to provide a foundation for future critical explorations of this facet of diary research. The research that this paper is based on involved a 12-month diary-interview study. This project explored the employability management of Chinese international Master’s students in social sciences studying in the UK during one academic year. The article sets out key facets of diary-keeping behaviour and explores specific considerations for diary studies in higher education contexts, where diary research has been particularly neglected

Thermal aware task assignment for multicore processors using genetic algorithm

Microprocessor power and thermal density are increasing exponentially. The reliability of the processor declined, cooling costs rose, and the processor's lifespan was shortened due to an overheated processor and poor thermal management like thermally unbalanced processors. Thus, the thermal management and balancing of multi-core processors are extremely crucial. This work mostly focuses on a compact temperature model of multicore processors. In this paper, a novel task assignment is proposed using a genetic algorithm to maintain the thermal balance of the cores, by considering the energy expended by each task that the core performs. And expecting the cores’ temperature using the hotspot simulator. The algorithm assigns tasks to the processors depending on the task parameters and current cores’ temperature in such a way that none of the tasks’ deadlines are lost for the earliest deadline first (EDF) scheduling algorithm. The mathematical model was derived, and the simulation results showed that the highest temperature difference between the cores is 8 °C for approximately 14 seconds of simulation. These results validate the effectiveness of the proposed algorithm in managing the hotspot and reducing both temperature and energy consumption in multicore processors

Performance analysis of multicore processors using multi-scaling techniques

Integrating more cores per chip enables more programs to run simultaneously, and more easily switch from one program to another, and the system performance will be improved significantly. However, this current trend of central processing unit (CPU) performance cannot be maintained since the budget of power per chip has not risen while the consumption of power per core has slowly reduced. Generally, the processor’s maximum performance is proportional to the product of the number of their cores and the frequency they are running at. However, this is usually limited by constraints of power. In this study, first, the voltage/frequency adjustment of the running cores has been analyzed for several programs to improve the processor’s performance within the constraint of power. Second, the impact of dynamically scaling the number of running cores is summarized for additional performance improvements of the active programs and applications. Finally, it has been verified that scaling the number of the running cores and their voltage/frequency simultaneously can improve the processor’s performance for a higher power dissipation or under power constraints. The performance analysis and improvements are obtained in a real-time simulation on a Linux operating system using a GEM5 simulator. Results indicated that performance improvement was attained at 59.98%, 33.33%, and 66.65% for the three scenarios, respectively

Testing self-report time-use diaries against objective instruments in real time

This study provides a new test of time-use diary methodology, comparing diaries with a pair of objective criterion measures: wearable cameras and accelerometers. A volunteer sample of respondents (n = 148) completed conventional self-report paper time-use diaries using the standard UK Harmonised European Time Use Study (HETUS) instrument. On the diary day, respondents wore a camera that continuously recorded images of their activities during waking hours (approximately 1,500–2,000 images/day) and also an accelerometer that tracked their physical activity continuously throughout the 24-hour period covered by the diary. Of the initial 148 participants recruited, 131 returned usable diary and camera records, of whom 124 also provided a usable whole-day accelerometer record. The comparison of the diary data with the camera and accelerometer records strongly supports the use of diary methodology at both the aggregate (sample) and individual levels. It provides evidence that time-use data could be used to complement physical activity questionnaires for providing population-level estimates of physical activity. It also implies new opportunities for investigating techniques for calibrating metabolic equivalent of task (MET) attributions to daily activities using large-scale, population-representative time-use diary studies

How long should a diary be kept? : A diary study of prospective and retrospective memory errors in young and old healthy adults

Memory research has commonly been conducted in the laboratory, and by the use of self-report questionnaires assessing retrospective and prospective memory. Although a diary method can give more accurate insight into everyday memory processes, there are very few diary studies of everyday memory errors. This study added a 28-day diary-recording period to laboratory tests and self-assessment questionnaires. The 28 day period was expected to cover different aspects of life – busier and quieter periods – but initial results showed that surprisingly few memory errors were recorded over a 28 day period, yet participants claimed to have been recording the majority of memory errors experienced during this period. We suspect that participants fatigue over 28 days or start slowly because they feel they have plenty of time, and therefore record fewer errors. A second 7-day diary condition was added and results will compare the number of memory errors committed pro rata over the two diary-keeping periods.Peer reviewedFinal Accepted Versio

The Prediction of the Electromagnetic Properties and the ?(E2/M1) of 110-116Cd-Isotopes in IBM Model

The Nuclear structure of 110-116Cd isotopes was studied theoretically in the framework of the interacting boson model of IBM-l and IBM-2. The properties of the lowest mixed symmetry states such as the 1+, 2+ and 3+ levels produced by the IBM-2 model in the vibrational-limit U(5) of Cd - isotopes are studied in details. This analysis shows that the character of mixed symmetry of 2+ is shared between and states in 110-114Cd – isotopes, the large shar goes to s, while in isotope, the state is declared as a mixed symmetry state without sharing. This identification is confirmed by the percentage of F-spin contribution. The electromagnetic properties of E2 and Ml operators were investigated and the results were analyzed. Various values of eB in the IBM-l and fixed e?= 0.104 eb and e?=0.093 e.b in the IBM-2 are used to generate the B(E2) and Q(2+). Fixed values of g? =0.31?N and g? =-0.31?N were adopted to generate the B(Ml) and ?(E2/ Ml) mixing ratios. The small values of ?(E2/Ml) which obtained for transition from MS- states to those of full symmetry support the conclusion that there may be a strong Ml transition between these states
