Rock typing in carbonate reservoirs has always represented a difficult challenge due to rock heterogeneity. When interpreting electrical logs, the thick carbonate formation can leave an impression of a homogenous environment; however, looking at core analysis and mercury injection capillary pressure (MICP) data, reservoir heterogeneity can be determined. This complexity of the formation characterization presents challenges in reservoirs that contain tilted water/oil contact (WOC). Tilted WOC discovers hydrocarbon saturation below the free-water level, and different events during geological time can contribute to this specific fluid accumulation. Knowledge of the fluid distribution is needed to understand the mechanisms of oil entrapment, oil volumetrics, and potential recovery mechanisms involved in reservoirs under this wettability and WOC conditions. This case study will describe the workflow used to characterize and model an atypical regime like non-water wet formations in reservoirs with tilted WOC. In this study, a combination of electrical logs, core analysis (lithofacies, poro-perm, MICP), and customized workflow was used to characterize, classify, and map facies. Capillary pressure information and formation tester data were integrated and compiled for each facies. Moving forward, a new method was developed to model saturation height functions representing non-water wet formations and tilted WOC phenomena. Fluid and saturation properties are estimated and assigned to each reservoir point and after reservoir rock types (RRT) were defined. This method has been validated by applying the new approach to actual well data. The drainage capillary pressure (Pc) lab data in the reservoir intervals with established conventional WOC complemented interpretation results derived from acquired logs; however, for the reservoirs zones with identified tilted WOC, correlation and matching Pc lab data with logs was not possible. The new method provides saturation properties in formations with complex fluid-rock interactions and phenomena. This work introduces a novel approach to estimate saturation height functions and saturation distribution for reservoirs with complex fluid-rock interaction and distribution, such as non-water wet formations in tilted WOC conditions.
Rejection of Accident Insurance Claims by Insurance Companies
Authors: Samudera Berto Tegar
Published: August 2021

Insurance is a form of compensation for the occurrence of uncertain risks and the delegation of responsibility to bear those risks. The event of this risk is uncertain because it depends on uncertainty. The transfer of risk is carried out by making an insurance agreement or insurance agreement. The first party is usually referred to as the insured. The second is the party willing to accept the risk of the first party by accepting a payment called a premium. Risk takers are often referred to as insurance companies. The research method used in this study uses a legal approach research method (statute approach) and a conceptual approach (conceptual approach). Based on the results of this study, the researcher states that the basis or cause of the rejection of an insurance agreement is because the insurance agreement is a conditional agreement, where the insurer only bears the loss suffered by the insured party following the terms of the event that resulted in the loss to the insured as agreed, by the parties in the insurance agreement. Or the insured party does not carry out its obligations to pay premiums to the insurer. The legal remedy that the insured party can take if the insurer rejects the claim is to file a lawsuit at the local District Court, as regulated in Article 23 of Law no. 8 of 1999. It can be completed through the BMAI institution.Keywords: Insurance, Claim, Dispute Resolution.

Method for optimization of frequency resource allocation with frequency reuse for cognitive radio system
Authors: Kolyadenko Yu.Yu. , Kolyadenko О.V. , Mulyar B.P.
Published: August 2021

The concept of cognitive radio can be described as a radio with the study of capabilities, i.e. as a radio that is able to gain knowledge about the radio environment and adjust its operating parameters and protocols accordingly.

The task of minimizing the frequency band is relevant at the stage of the cognitive radio network functioning when distributing the frequency resource between subscriber stations. With the ever-growing demand for frequency bands, this challenge is driven by the need to improve the efficient use of the radio frequency spectrum through frequency reuse methods.

This paper proposes a method for ensuring the reuse of frequencies based on obtaining estimates of mutual distances between subscriber stations in real time. An algorithm is proposed for solving the problem of frequency resource allocation optimization for a cognitive radio network with frequency reuse. The algorithm is based on the method of local optimization, one of the approximate methods of discrete programming. In this case, the condition of local optimality is that the operating frequency assigned to the next subscriber station must be the closest to the frequency assigned in the previous step.

The efficiency of the frequency resource optimization algorithm for the LTE network was analyzed using simulation modeling. The dependences of the bandwidth on the number of subscriber stations served are obtained. The analysis showed that the use of this algorithm allows to reduce the frequency band by 2 -3 times. The analysis also showed that the efficiency of the algorithm increases with the growth of the number of subscriber stations served simultaneously.
Architecture of network knowledge base of a complex military system

Published: August 2021

The article examines the architecture of a networked knowledge base and the organizational structure of a complex military-purpose system, which is built when a group of troops (forces) is created and kept in a state where it is capable of solving the tasks assigned to it. This requires a deep study of issues not only of modern tactics regarding the preparation and conduct of hostilities, but also more complex issues of scientific substantiation of the architecture of a networked knowledge base and the structure of a complex military system with a networked knowledge base. The internal representation of knowledge in the knowledge base (formal programmatic and logical content) is advisable to implement in the form of an adjacency matrix, which displays the relationship and relationship between target settings; initial conditions; the resources of the grouping of troops (temporary, material, combat and quantitative composition), their costs and replenishment; rules for the use of resources and the choice of criteria for their distribution. The knowledge base synthesizes a mathematical network model for making decisions, which provides a change (correction) of the structure of target attitudes when replenishing the knowledge base. Tasks solved in the knowledge base: selection of vertices and relations when replenishing catalogs; making changes to the adjacency matrix in accordance with the identified or changed relationships between targets. A necessary element of the synthesis of a mathematical network model for making decisions on the preparation and conduct of hostilities is the construction of the structure of the target systems of the system for a specific situation. A feature of controlling the correctness of knowledge presented in the form of target attitudes is the need for a joint analysis of the entire set of target attitudes and initial conditions in their relationship. For this, the matrix of the relations of target attitudes and the matrix of the relations of initial conditions are combined. The control of the correctness of the knowledge base is carried out when replenishing the knowledge base, it includes: identification of contradictions in the structure of target attitudes when making changes to this structure; search and detection of contradictions in the graph of the semantic network according to available resources and time; checking the completeness of the graph of the mathematical network model; issuance of revealed contradictions to an expert and their elimination. A practical approach to building the architecture of a networked knowledge base and the organizational structure of a complex military system can be implemented during the substantiation of the components and elements of the system when creating a grouping of troops (forces).

Search and analysis of results of theoretical and experimental studies, materials of dissertations, literature sources and patents in the field of optical and optoelectronic instrumentation were carried out. Obtained data and recommendations on the development of methods for dispersing nanoparticles into polymer matrices for the creation of optically transparent nan composites for use in many fields of science and technology are generalized. Analysis of considered results makes it possible to conclude that for creating hybrid organic-inorganic composites with high level of dispersion of inorganic component, it is necessary to solve problems relating to compatibility of components and stabilization of filler nanoparticles in polymer matrix. Due to the limited range of hydrophilic polymers capable of forming composites with nanoparticles without stabilizers, the main approaches to the preparation of hybrid composites are using modifying additives of surfactants, as well as complex chemical reactions on the surface of inorganic filler nanoparticles. Such methods of obtaining nanocomposites with nanoparticles are laborious and involve formation of by-products and additional purification. It is shown that titanium dioxide (TiO2) and zinc oxide (ZnO) are of great interest among a large number of nanodispersed fillers of polymer matrices in preparing composite materials. There are many methods for synthesis of ZnO and TiO2 nanoparticles with various shapes and sizes, including laser ablation method, which is convenient and universal method for preparing nanosuspensions of solid-phase materials in liquid. Advantages over other methods for nanoparticle synthesis, such as the simplicity of method, environmental friendliness, low cost, and the ability to obtain cleaner colloidal solutions without using surfactants and other impurities, have made laser ablation in a liquid medium very popular among researchers.

The system of equations for processes in the amplifier output network is analytically formulated. This system of equations considers parameters of resonant networks at higher harmonics. To calculate amplifier output network, the system of five equations was built for five unknowns, to which the condition of positive second voltage derivative at extremum of drain voltage was added. Two equations correspond to class E conditions, another two — quadrature waveforms at load and at additional resonant network. The last equation is the condition of extremum at the point near middle of drain voltage pulse. This system was solved using computer algebra program. The circuit elements and waveforms were calculated using the derived parameters. By choosing different parameters, it is possible to obtain various amplifier realizations, which will demonstrate features of different class F variants. The obtained amplifier parameters drain voltage and current waveforms were verified with calculated ones using the harmonic balance simulating software. The variant, which is closer to class E/F3 mode, was chosen to build an experimental amplifier prototype on frequency 2MHz using IRF530 MOSFET as a switch. The prototype was tested in the range of supply dc voltage up to 24V with the output power greater than 6W, while the amplifier efficiency was >80%. In the experiment, the ratio of peak drain voltage to dc supply voltage was measured to be 3.3 at the duty ratio 50%, unlike class E amplifier, where this value is around 3.65, and on practice, considering non-linear drain to source capacitance, it may achieve 4. The experimental second harmonic level amounted to be -20 dB relatively to fundamental, and the third one — 28.5 dB, which is due to an additional second harmonic filter. The paper results are useful for introduction of such circuits to practice.

Authors: Ozhogin Vladyslav
Published: August 2021

The objective: optimization of approaches to the choice of endoscopic ureterolithorpsy method in the presence of large stones of the proximal ureter.
Materials and methods. For the period 2017–2020 y. the study included 136 patients with large stones of the proximal ureter, who were performed one of two methods of ureterolithotripsy: rULT (group I) or m-aULT (group II). In group I 73 (53,7%) patients were operated, in group II – 63 (46,3%) patients. The age of patients ranged from 18 to 81 years, the average age was 52,7 years (54±10,5). The age of patients in group II ranged from 25 to 77 (63±10,5) years; the size of a concrement from 10 to 20 (14±3,5 mm). In group I, the age of patients ranged from 18 to 91 (63,5±10 years); the size of a concrement from 7 to 20 (12±5,5 mm).
Results. The average time of m-AULT was 58,5±15,4 min, while the status of stone free was achieved in all 100% of patients. The operation ended with the installation of nephrostomy drainage in 11 (17,5%) cases, nephrostomy drainage and internal ureteral JJ-stent – in 33 (52,4%), in 19 (30,2%) cases – tubeless drainage method with the installation of ureteral stent. And the total percentage of stenting in staghorn stones of the proximal ureter, after lithotripsy and litholapaxy was 82,6% (52 patients). RULT surgery in 92% (67 patients) of cases ended with drainage of the kidney by JJ-stent, in 6 (8%) patients the operation ended without drainage.
Conclusions. Analyzing the results, it was noted that the antegrade approach is a safe and effective method of treatment for proximal ureterolithiasis in the group with large stones of the proximal ureter, where the effectiveness of RULT (SFR up to 86,3±3,9%) is significantly inferior to AULT, and minimizing the size of instruments m-aULT) reduces the number and degree of complications associated with the size of the coiled tract, while providing a high level of SFR (96,8±4,4%).

PATRON-CLIENT SOCIAL RELATIONSHIP BETWEEN PALM OIL FARMERS AND TAUKE IN KREUNG ITAM VILLAGE TADU RAYA DISTRICT NAGAN RAYA DISTRICT
Authors: Maifianti Khori Suci , Darmansyah Dedy , Muslimin Ikhwanul
Published: August 2021

Krueng Itam village is one of the villages where the majority of the residents work as palm oil farmers and depend on palm oil plantations. In marketing to sell FFB (Fresh Fruit Bunch) palm oil farmers still rely on collector traders (agents) which in this case is referred to by the term "Tauke Sawit" (toke sawit). In the beginning, the relationship between palm oil farmers and the Tauke was limited to economic relations, such as the sale and purchase relationship between sellers and buyers. But in its development, the relationship turns into a relationship of dependence and interest that leads to a patron-client relationship. This study used a descriptive qualitative method with data collection techniques through observation and interview process that is expected to be able to provide an overview of the social relationship between tauke and farmers. Based on the results of the study, the relationship between tauke and palm oil farmers is a patron- client relationship where palm oil tauke as the patron and palm oil farmers as clients. Palm oil farmers need tauke to accomodate the harvest of palm oil FFB and tauke needs palm oil FFB from farmers to be sold to Palm oil mills. In this cooperative relationship, farmers will usually borrow money for capital needs and others to the tauke, this makes the farmers' dependence on the tauke become greater so that each of them will maintain the relationship by respecting the existing norms so that the relationship has been established will not be broken easily. The relationship of patron-clients is more visible in the relationship between tauke and small farmers, this is because there is a clear difference in socio-economic status between the two, so that the tauke as a patron play a big role.
