The layout applied on the production floor of the Department of Mechanic of PT. Jefta Prakarsa Pratama is not considered as an optimal layout. The reason triggered this optimal level, are some backtrack movements that reduce the effectiveness and efficiency of material handling activities. This research refers to two types of calculation methods. First, manual calculation, which is rectilinear distance measure. Second, computerized calculation, which is Quantitative Systems (QS) software. There are three critical criterias referenced in this research, i.e. straight flow of material, more minimal backtrack movement, and more minimal material moving distance. The iteration results using QS software are translated into block layout and then are made as a proposed layout. The rectilinear calculations performed manually are intended to calculate the total of material moving distance. The data processing obtained a re-layout solution which is more optimal for the production floor of the Department of Mechanic, because it could reduce backtrack distance by 75.28% and the material moving distance by 30.03%. The implementation of the proposed layout is expected to reduce the time of material moving activity on the production floor of the Department of Mechanic, so that the material moving process could run more effectively and efficiently.

The present study analyzes the difference between the Åland Islands — an insular and peripheral part of Finland — and Finland as a whole in terms of firm local embeddedness. The analysis utilizes matched employee-employer longitudinal data for all businesses in Finland, including the Åland Islands, from 2006 to 2014. Local embeddedness is modelled both as tenure (the number of years a key stakeholder in a firm has lived in the same municipality as the firm) and by calculating the geographical distance the key stakeholder lives from the focal firm. Contrary to our expectations, we find that for our tenure measure of local embeddedness, firms are actually less locally embedded in the peripheral region than in the larger country. However, our distance measure of local embeddedness performs as expected with firms in the peripheral region. We hypothesize that that there may be an optimal level of local embeddedness, above which a local firm does not necessarily gain by further increasing its local embeddedness.

SummaryA system consisting of an 8-bit word microcomputer of the APPLE line equipped with an analog-to-digital converter, connected to a physiograph measuring pressures from a whole-body Plethysmograph, was used to perform pulmonary tests in rats. The system proved to be time-saving without loss in accuracy when compared to manual calculation methods. It allows measurement repetition during the same experiment, which is impossible by manual techniques, and permits to obtain flow/volume relationships without pneumotachographs or integrator and/or differentiator modules. This approach may be applied to humans and used by any physician.

Electricity that produced by renewable energy sources are countinously increased, but some place in Indonesia have not utilize the renewable sources maximally, for instance Kolorai, South Morotai. Based on data from NASA, solar radiation in kolorai is around 5,99 kWh/m2/day, so solar power plant is one of solution to solve electricity needs in remote area like Kolorai. Futhermore, in solar power plant project, determining the load profile and designing the stand alone PV with simulation is important to make a great system. So the optimal methods are needed to build those system, the methods that have higher energy output, less excess energy, dan have a low Net Present Cost. In this paper, Australian/New Zealand standart and manual calculation are used to create an economical design. The result of the HOMER simulation shows that using Australian/New Zealand standart have a suitable result with excess electricity value is 8,56% and Net Present Cost is 1.439.160.000 rupiah.

The Nuclear Material Accounting (NMA) system is one of the main safeguards measures to detect the existence of nuclear material diversion. It has become more important for large reprocessing facilities to apply Near Real Time Accountancy (NRTA) system based on NMA and statistical techniques to meet quantitative and timeliness goals. It is also important to quantitatively evaluate the performance of NMA system including NRTA from the standpoints of Safeguards and Security by Design (SSBD) prior to construction of nuclear-material-handling facilities. Such evaluation improves safeguards effectiveness and efficiency. Modeling and Simulation (M&S) work is a good way to evaluate performance for various NMA systems and to determine the optimal one among different options. For these purposes, in the present study, the PYroprocessing Material flow and MUF Uncertainty Simulation+ (PYMUS+) code, which uses evaluation algorithms to calculate many safeguards factors such as MUF uncertainty, detection probability, and others, was developed. According to a previous report, the PYMUS code, the predecessor of PYMUS+, can calculate MUF uncertainties only for a fixed model having 10 tHM/year, whereas the PYMUS+ code can additionally calculate detection probabilities according to diverse nuclear diversion scenarios as well as MUF uncertainties. The most important feature of the PYMUS+ code is its capability to evaluate many process and NMA system model options that a user wants to evaluate. Furthermore, a user can make a static process model having simplicity and a matching NMA model based on the PYMUS+ code regardless of facility throughput and is not even required to have professional programming knowledge. In the present work, some intercomparative studies were conducted to verify the M&S techniques applied in this code. It is expected that this code will be a useful tool for evaluation of NRTA system of pyroprocessing and other reprocessing facilities.


This paper provides a general indication of the existing approaches rely on basic factor (i.e. extraction of iris information, affine transform, and distance matrix) as input. An essential factor in effective design of IRIS based biometric approach is the accuracy with which the model can estimate a region of interest (i.e. IRIS) within constraints and unforeseen issues, which can be very problematical but need of the hour. We introduced a new IRIS based biometric system that incorporates various factors that takes complete information of eye for developing the feature set (digest) while affine transforms are not incorporated while the three sets distance measure is incepted to enhance accuracy. The algorithm-based size of template, functionality of distance measure and/or scope, methods and/or function of application through well-defined scientific and statistical principles. Unfortunately, the accuracy of the existing approaches is limited despite the large scale of experience with several improvements based on digital image processing and statistical models. Henceforth, we incorporated several texture analysis algorithms with computing techniques along with several parametric enhancement constraints to ensure the feasibility, effectiveness and efficiency of the proposed framework in comparison with the existing methods.

As computer components become smaller the analytical methods used to examine them and the material handling techniques must become more sensitive, and more sophisticated. We have used microbulldozing and microchiseling in conjunction with scanning electron microscopy, replica electron microscopy, and microprobe analysis for studying actual and potential problems with developmental and pilot line devices. Foreign matter, corrosion, etc, in specific locations are mechanically loosened from their substrates and removed by “extraction replication,” and examined in the appropriate instrument. The mechanical loosening is done in a controlled manner by using a microhardness tester—we use the attachment designed for our Reichert metallograph. The working tool is a pyramid shaped diamond (a Knoop indenter) which can be pushed into the specimen with a controlled pressure and in a specific location.
