This paper study the determination of the number submarine defenses for Indonesian archipelago underwater defenses with probability method approach. In performing these calculations the authors perform the processing of data from various sources, both from the literature, the data from the relevant authorities in this regard Operations staff, Submarine Force with the elements in the form of operating reports, obtained through interviews and from the field. From these data processed probability calculation and the result obtained is inserted into the formula length / width of the waiting area submarine patrol positions further implemented method of calculating the probability to obtain optimal results. The result of this study is to know the total number of submarines are needed to maintain the strategic straits Indonesia as much as 13 submarines. With the percentage of each strategic submarines: 23% Makassar Strait (3 Submarines), the Lombok Strait 15.4% (2 Submarines), Strait of Halmahera 30.77% (4 Submarines), Wetar Strait 15.4% (2 Submarines), Strait Ombai 15.4% (2 Submarines). If there is a dynamic field that can easily be placed in the strait Submarines received threats in accordance with the percentage division. Suppose a threat occurs only in Hot Area I (Makassar Strait and the Strait of Lombok) then placed Submarines strength at 35.4% (5 Submarines).Keywords: Submarine, Probability Concepts, Determination of Total submarine

Morphological Differences

It has been demonstrated that cross sections of bundles of hair can be effectively studied using image analysis. These studies can help to elucidate morphological differences of hair from one region of the body to another. The purpose of the present investigation was to use image analysis to determine whether morphological differences could be demonstrated between male and female human Caucasian terminal scalp hair.Hair samples were taken from the back of the head from 18 caucasoid males and 13 caucasoid females (Figs. 1-2). Bundles of 50 hairs were processed for cross-sectional examination and then analyzed using Prism Image Analysis software on a Macintosh llci computer. Twenty morphological parameters of size and shape were evaluated for each hair cross-section. The size parameters evaluated were area, convex area, perimeter, convex perimeter, length, breadth, fiber length, width, equivalent diameter, and inscribed radius. The shape parameters considered were formfactor, roundness, convexity, solidity, compactness, aspect ratio, elongation, curl, and fractal dimension.

The effect of fractal dimension (Df) on the determination of representative elementary volume (REV) was investigated through numerical experimentations, in which a new method was adopted to extract submodels that have different length-width ratios from original discrete facture networks (DFNs). Fluid flow in 1610 DFNs with different geometric characteristics of fractures and length-width ratios was simulated, and the equivalent permeability was calculated. The results show that the average equivalent permeability (KREV) at the REV size for DFNs increases with the increase in Df. The KREV shows a downward trend with increasing length-width ratio of the submodel. A strong exponent functional relationship is found between the REV size and Df. The REV size decreases with increasing Df. With the increment of the length-width ratio of submodels, the REV size shows a decreasing trend. The effects of length-width ratio and Df on the REV size can be negligible when Df≥1.5, but are significant when Df<1.5.

A new method for extracting junction parameters of the single diode model is presented. A least squares method approach considers the deviation ∆V=f(I) between the experimental current-voltage (I-V) characteristic and a theoretical arbitrary characteristic. A specific case- the ∆V graph reducing to a straight line–is identified and the knowledge of the slope and of the intercept with the ordinate axis leads to the determination of the junction parameters. The method is applied to the characterization of the emitter-base junction of transistors and the results are discussed.

Indonesia as an archipelagic country is gifted by God with a geographical location between two continents and also two oceans, making Indonesia's position very strategic. In accordance with UNCLOS 1982, as an archipelagic country, Indonesia has an obligation to provide a shipping route called ALKI (Indonesian Archipelago Sea Channel). ALKI 1 stretches from the Malacca Strait to the Sunda Strait. The Sunda Strait as one of the busy shipping lanes is vulnerable to various forms of threats. To ensure the safety of shipping in the Sunda Strait, the TSS of the Sunda Strait is designated as a shipping lane separating channel. With the determination of the TSS of the Sunda Strait, shipping using the Sunda Strait will be increasingly crowded, this will pose an even greater threat. The purpose of this study was to analyze the strengthening of the marine defense strategy in the Sunda Strait carried out by Lanal Banten by utilizing the TSS of the Sunda Strait. The method used in this research is descriptive qualitative research using the theory of policy implementation from Van Meter Van Horn and strategy theory from Lykke. The results of the study indicate that the lack of facilities and infrastructure and the absence of a special operation carried out by the Indonesian Navy to secure the Sunda Strait, so that the implementation of strengthening the marine defense strategy in the Sunda Strait has not been optimal. There needs to be support for facilities and infrastructure as well as support for special operations in the Sunda Strait to strengthen the maritime defense strategy in the Sunda Strait and the participation of the people around the Sunda Strait.

This paper proposes a cost function approach to predict the passenger distribution at the platform, which is contributed to provide services to the passenger safety and convenience and also an efficient use of the subway platform. According to the limited observation and field data collection of Beijing Xuanwumen subway station, passenger behaviors and basic attributes at the platform are analyzed. Based on the analysis and investigation, factors including the distance to the waiting area, the passenger density in the visual field, and the length of the waiting area occupied by passengers are put forward as important factors to affect the choice of the waiting area. The determination of the real-time choice defined by these factors is applied to model the passengers’ waiting area choice behaviors. Simulation experiments are run for the model calibration and validation combining with the collected field data. The results show that the passenger distribution which arises from the model is capable of keeping consistent with the actual distribution in the rough. The model is helpful for controlling how heavy carriages are congested and providing suggestions to optimize the layout of platform facilities.

Digital Speckle

Pulse diagnosis is one of the four diagnostic methods of traditional Chinese medicine. However it suffers from the lack of objective and efficient detection method. We propose a noncontact optical method to detect human wrist pulse, aiming at the precise determination of the temporal and spatial distributions of pulse. The method uses the spatial-carrier digital speckle pattern interferometry (DSPI) to measure the micro/nanoscale skin displacement dynamically. Significant improvements in DSPI measurement have been made to allow the DSPI to detect the comprehensive information of the arterial pulsation at locations of Cun, Guan, and Chi. The experimental results prove that the spatiotemporal distributions of pulse can be obtained by the proposed method. The obtained data can be further used to describe most of the pulse parameters such as rate, rhythm, depth, length, width, and contour.

Multiple Diagnosis

Bayesian formula is used to determine diagnosis sequence when several fault trees meet requirements. Bayesian prior probability is usually determined through expert or the user's subjective judgment and historical experience. If there is lack of expert experience, the determination of priori probability is very difficult. A real-time priori probability calculation method is proposed, which needn’t any priori-knowledge and can regulate automatic on the monitoring parameters. It takes into account the multiple diagnosis impact and more flexible than fixed priori probability according application.
