Effective Use

One of the indicators of the effective use of artillery is the accuracy of the fire impact on the objects of enemy. The accuracy of the artillery is achieved by completing the implementation of all measures for the preparation of shooting and fire control. Main measures of ballistic preparation are to determine and take into account the summary deviation of the initial velocity. The existing procedure for determining the summary deviation of the initial velocity for the check (main) cannon of battery leads to accumulation of ballistic preparation errors. The supply of artillery units with means of determining the initial speed of the projectile is insufficient. Among the many known methods for measuring the initial velocity, not enough attention was paid to the methods of analyzing the processes that occur during a shot in the "charge-shell-barrel" system. Under the action of the pressure of the powder gases in the barrel channel and the forces of the interaction of the projectile with the barrel there are springy deformations in the radial direction. To measure springy deformations it is advisable to use strain gauge sensors. Monitoring of deformation in a radial direction by time can be used to determine the moment of passing a projectile past the strain gauge mounted on the outer surface of the barrel. In the case of springy deformations, the initial resistance of the sensor varies in proportion to its value. The speed of the shell (mine) in the barrel can be determined by time between pulses of signals obtained from strain gauges located at a known distance from each other. The simplicity of the proposed method for measuring the initial velocity of an artillery shell provides an opportunity for equipping each cannon (mortar) with autonomous means for measuring the initial velocity. With the simultaneous puting into action of automatic control systems can be automatically taking into account the measurement results. This will change the existing procedure for determining the total deviation of the initial velocity and improve the accuracy, timeliness and suddenness of the opening of artillery fire, which are components of its efficiency.

Pollaczek's theory for the many server queue is generalized and extended. Pollaczek (1961) found the distribution of the actual waiting times in the model G/G/s as a solution of a set of integral equations. We give a somewhat more general set of integral equations from which the joint distribution of the actual waiting time and some other random variables may be found. With this joint distribution we can obtain distributions of a number of characteristic quantities, such as the virtual waiting time, the queue length, the number of busy servers, the busy period and the busy cycle. For a wide class of many server queues the formal expressions may lead to explicit results.

The Bootstrap Method

A common way to calculate the glitch activity of a pulsar is an ordinary linear regression of the observed cumulative glitch history. This method however is likely to underestimate the errors on the activity, as it implicitly assumes a (long-term) linear dependence between glitch sizes and waiting times, as well as equal variance, i.e., homoscedasticity, in the fit residuals, both assumptions that are not well justified from pulsar data. In this paper, we review the extrapolation of the glitch activity parameter and explore two alternatives: the relaxation of the homoscedasticity hypothesis in the linear fit and the use of the bootstrap technique. We find a larger uncertainty in the activity with respect to that obtained by ordinary linear regression, especially for those objects in which it can be significantly affected by a single glitch. We discuss how this affects the theoretical upper bound on the moment of inertia associated with the region of a neutron star containing the superfluid reservoir of angular momentum released in a stationary sequence of glitches. We find that this upper bound is less tight if one considers the uncertainty on the activity estimated with the bootstrap method and allows for models in which the superfluid reservoir is entirely in the crust.

Perhaps the most famous anecdote of the many connected with the reign of Tsar Nicholas I concerns the way in which he supposedly determined the route of the St. Petersburg-Moscow Railway. When asked by his officials the route along which it should be built, the tsar, on the spur of the moment, it is claimed, took a ruler, laid it on a map, and arbitrarily and hastily drew an absolutely straight line between the two capitals. The all-powerful despot had spoken, and his decision was carried out by his servile courtiers, regardless of consequences.

Seldom has a scientific or biomedical break-through evoked the awe, controversy, or sheer incredulity that has accompanied the developments in the field of recombinant DNA technology or more popularly, gene cloning and genetic engineering. Now little more than one generation after Avery, et al1 demonstrated that genes were encoded in DNA and Watson and Crick2 interpreted the structure of these molecules, genes are being cut, manipulated, and recombined to produce unprecedented new insights into genetics and molecular biology and the prospect of gene therapy. These developments have not occurred without anxiety to both scientists and laymen. At the moment, neither the most apocalyptic fears nor the most optimistic dreams appear to be imminent, although I believe that the dreams are closer to fulfillment than the fears. Recombinant DNA technology is already having great impact in hematology, oncology, endocrinology, immunology, and infectious disease and will soon play an important role in other medical subspecialities as well. In none, however, will it have quite the same impact as in genetics because DNA is the material that genetics "is all about." The cloning and study of phenylalanine hydroxylase is one of the first instances in which this technology has important implications in the diseases traditionally classified as inborn errors of metabolism. In order to understand and appreciate the presentation by Woo on phenylalanine hydroxylase as well as the many future papers that will play so vital a role in all of our professional lives, it is necessary to acquire the basic vocabulary of the field.

The Temple

This case examines the queueing issues caused by the growth in popularity of one of the most visited Hindu temples in the world. On January 2, 2015, Ramesh and Vasantha Gupta visit Tirumala Venkateswara Temple, just a day after some 210,000 people crowded the 2,000-year-old site. The case describes the many enhancements that the temple administrator, Tirumala Tirupati Devasthanams (TTD), has implemented since its management of the temple complex began in 1932. The soaring popularity of the temple, however, has led to safety and comfort concerns for pilgrims. While challenging students to consider additional improvements that might benefit pilgrim throughput rate and time in the temple system, the case highlights the tension TTD must manage between maximizing efficiency and maintaining religious traditions. Additionally, the case demonstrates the importance of perceived waiting times in the management of queues.

Maintenance Service

The aims of this paper are (1) to identify the characteristics of maintenance service providers that directly impact maintenance service quality, using 18 independent covariables; (2) to quantify the change in risk these covariables present to service quality, measured in terms of equipment turnaround time (TAT). A survey was applied to every maintenance service provider (n = 19) for characterization purposes. The equipment inventory was characterized, and the TAT variable recorded and monitored for every work order of each service provider (N = 1,025). Finally, the research team conducted a statistical analysis to accomplish the research objectives. The results of this study offer strong empirical evidence that the most influential variables affecting the quality of maintenance service performance are the following: type of maintenance, availability of spare parts in the country, user training, technological complexity of the equipment, distance between the company and the hospital, and the number of maintenance visits performed by the company. The strength of the results obtained by the Cox model built are supported by the measure of the Rp,e2 = 0.57 with a value of Rp,e= 0.75. Thus, the model explained 57% of the variation in equipment TAT, with moderate high positive correlation between the dependent variable (TAT) and independent variables.

Production scheduling is the most important part in carrying out the production process that will be carried out on a production floor. Scheduling activities are carried out before the production process begins to ensure the smooth running of the production process. If the production scheduling is not done properly, there will be obstacles in the production process and will cause losses to the company. This study aims to determine the production machine scheduling in a company engaged in the manufacture of spare parts for automotive products. This company implements a job shop production process and uses the First In First Out method in completing its work. Due to the large number of products that have to be produced, there are often two or more products that must be worked on at the same time and machine. This condition causes some products to have to wait for the associated machine to finish operating and causes long product turnaround times. This problem is solved by making a production machine scheduling using the Non-Delay method. By applying this method, the makespan of completion time can be minimized.

Vocational High School or in Indonesian abbreviated as SMK, is a government program that was built with the aim that students can have expertise in certain fields and can be the initial capital for them in looking for work. An accredited educational curriculum and the many practical activities provided to students can also ensure that SMK graduates are ready to enter the workforce. However, in today's world of work, it requires workers who, in addition to having skills, must also have work experience. There are events held by the government regarding Job Vacancy info which are held only a few times a year so that more participants are participating and the unemployment rate in the regions is getting higher. Based on the above problems, the authors provide a solution by creating a "Freelance Service Provider Application" which is expected to bring together workers and job seekers. The application is made web-based so that it can be easily accessed through various types of devices. The author also implements Progressive Web Apps technology or also known as PWA so that it can be more easily accessed on mobile devices. Based on the results of the discussion on the implementation of PWA technology for making applications for freelance service providers, this can be a means for the public and prospective workers to meet and conduct transactions. So based on the questionnaire data obtained from the respondents, it can be concluded that the research carried out was successful and it is felt that it can help the graduates of SMK 3 Mataram to get jobs and also work experience
