Service Performance Evaluation in Large Railway Station in Indonesia

People need transportation for social and economic daily activities. Since road network usually experience traffic congestion, railroad is one of good alternatives. People will choose train as a public transportation if there is a good service performance. In accordance with domestic and International social and economic activities in Indonesia, national and International service standard is important. The aim of this study is to evaluate the service performance of large railway station in a large city in developing country. Bandung large railway station is carried out as a case study. Indonesian transportation minister regulation No. 48 year 2015 regarding people transport by train and Department for Transport Scotland, 2015 regarding design standards for accessible railway stations used as the standards. Results indicated that waiting room, boarding room, and prayer room fulfill the standards while restroom, lighting, and air-conditioner are unfulfilled. Furthermore, improvement, routine inspection, and maintenance have to be implemented consistently

Performance Evaluation of Centralized In-Network Caching and Content Visibility in Information Centric Network Over SDN/OpenFlow

Performance is the main issue that we must consider as the key point in order to design Information Centric Network architecture (ICN). Cooperative in-network caching and ability of network's nodes to see the contents in network will improve performance of ICN. In centralized network, the controller plays very important role in order to enable ICN nodes to do cooperative caching. Also, it has ability to see contents partially or globally according to our configuration. This paper aims to observe and compare the performance of ICN when we apply different levels of cooperative in-network caching and content visibility based on centralized control by using SDN/OpenFlow concept. We will evaluate performance of ICN by using three mechanisms; firstly, non-cooperative in-network caching with individual visibility; secondly, path cooperative in-network caching with path content visibility; and finally, global cooperative in-network caching with global content visibility. Our emulation result shows that global cooperative in-network caching with global content visibility mechanism gives better performance for ICN in terms of average number of hops to reach the content and number of requests hit server

Model-driven performance evaluation for service engineering

Service engineering and service-oriented architecture as an integration and platform technology is a recent approach to software systems integration. Software quality aspects such as performance are of central importance for the integration of heterogeneous, distributed service-based systems. Empirical performance evaluation is a process of measuring and calculating performance metrics of the implemented software. We present an approach for the empirical, model-based performance evaluation of services and service compositions in the context of model-driven service engineering. Temporal databases theory is utilised for the empirical performance evaluation of model-driven developed service systems

Physics and Performance Evaluation Group

We summarize the objectives and results of the ``international scoping study of a future neutrino factory and superbeam facility'' (ISS) physics working group. Furthermore, we discuss how the ISS study should develop into a neutrino factory design study (IDS-NF) from the point of view of physics and performance evaluation.Comment: 3 pages, 1 figure.

Performance Evaluation of Bacterial Cellulose Reinforced Polyethylene Composites

This paper discusses the influence of bacterial cellulose reinforced polyethylene composites on the physical and mechanical properties. Composites consisting of polyethylene and bacterial cellulose were prepared by extrusion and compression process. The content of bacterial cellulose subjected to polyethylene was set from 0-50 (w/w)% with the addition of 2% Polyethylene Maleic Anhydride (MAPE). The effect of bacterial cellulose content in the composites was evaluated. The tensile strength and elongation at break of composite declined with increasing of bacterial cellulose, but the Young\u27s modulus increased, demonstrating that composite becoming more rigid. At 23 oC 50%RH, tensile strength, break strain and modulus of elasticity of polyethylene was 21.2 MPa, of 270 % and 763 MPa respectively. With the bacterial cellulose loading up to 50%, tensile strength dropped to be half, break strain to be less than 0.5%, but Young\u27s modulus increased more than 230 %. In addition, the composite became more hydrophilic and more amorphous loading with bacterial cellulose

Evaluation the Performance Efficiency of Manufactured, Modified and Assembled Combine Implement and Studying It’s Impact on Some Soil Physical Properties and Total Costs

The experiment was conducted to evaluate the efficiency performance of the combine implement which manufactured and assembled locally and studying it\u27s effect on some soil physical properties and total costs in one of the Agricultural College University of Baghdad Experimental Fields in loamy soil, 2017. Brazilian Massy Ferguson Tractor (MF-650) was used with the combine implement as a machinery unit. Three machinery unit speeds included 3.15, 4.60 and 6.10 km/h and seedling treatments included manufactured combine implement, seedling and fertilizer implement and manual seedling were used in this experiment. Soil bulk density, soil moisture content, amount of added water and total costs were measured. Nested design under randomized complete block design with three replications was used in this experiment. Least significant differences (LSD = 0.05) level under 0.05 probability was used to compare treatment means. The results can be summarized as following: 1. Incrased machinery unit speeds from 3.15 to 4.60 km.h-1 led to significant increase in soil bulk density from 1.30 to 1.36 Mg.mˉ³and significant increase in soil moisture content from 0.18 to 0.20 %. 2. Manufactured combine implement treatment was superior in getting less soil bulk density stood 1.22 Mg.mˉ³ higher soil moisture content stood 0.22%.and less amount of added water during the season stood 1103.43 mm. and less costs stood 796370 Iraqi Dinars. 3. The interaction between 3.15 km.h-1machinery speed and manufactured combine implement got less soil bulk density stood 1.19 Mg.mˉ³, while the interference between 6.1 km.h-1 machinery unit speed and manufactured equipment was superior in obtaining a higher moisture content stood 0.229%. 4. Using the locally manufacturing modified combine implement for primary and secondary tillage, shallow furrow opener, seedling and fertilization in one time was successfully done in this study with high performance efficiency

PERFORMANCE MEASUREMENT AND EVALUATION

This chapter discusses methods and techniques for measuring and evaluating performance for the purpose of controlling the investment process. However, many of the methods discussed in this chapter are also used in communicating investment performance between the investment management company and it’s (potential) customers. Therefore, performance measurements also play an important role in the competition between investments management companies. Substantial evidence from the net sales of mutual funds shows that investors buy mutual funds with good past performance records although they fail to sell funds with bad past performance.Performance measurement; risk-adjusted performance
