This study aimed to conduct a needs assessment in order to design a CCTV camera placement plan in a barangay to enhance community safety and security. Employing a descriptive research design, the study involved 300 randomly selected respondents from a barangay in Talugtug, Nueva Ecija, Philippines. The results of the needs assessment underscored the importance of developing a CCTV camera placement plan for the barangay. The researcher proposed to develop a plan that aims to provide measures to improve safety and security within the community. Based on the needs assessment that has been conducted, several recommendations were drawn. Firstly, it was strongly advised to design a CCTV camera placement plan in the barangay. A follow-up study may be conducted focusing on this aspect. Future researchers must strategically place the CCTV in the area to optimize its full potential for securing the community. Secondly, community engagement and collaboration were highlighted as crucial factors for successful implementation, emphasizing the importance of involving community members, stakeholders, and educational institutions in the planning process. Thus, when designing a strategic CCTV placement plan, the involvement of various stakeholders is highly encouraged. Further, allocating resources for installation, maintenance, and monitoring was also proposed to ensure the sustainability and effectiveness of the surveillance system. Lastly, continuous evaluation and improvement of the CCTV camera placement plan when implemented is highly recommended, emphasizing the need for regular reviews, resident feedback, and performance monitoring to optimize the system's functionality. These recommendations provide valuable guidance for barangay officials in their pursuit of enhanced safety and security. By implementing the proposed plan that may be developed through this study and considering the input of the community, the barangay can create a safer environment and promote a sense of security among its residents.

Forecasting passenger flow at metro transit stations is a useful method for optimizing the organization of passenger transportation and enhancing operational safety and transportation efficiency. Aiming at the problem that the traditional ARIMA model has poor performance in predicting passenger flow, a hybrid prediction method based on ARIMA-Kalman filtering is proposed. In this regard, ARIMA model training experimental samples are integrated with Kalman filter to create a prediction recursion equation, which is then utilized to estimate passenger flow. The simulation experiment results based on the inbound passenger flow data of Nanjing metro station show that compared with the single ARIMA model, the root mean square error of the prediction results of the proposed ARIMA-Kalman filter hybrid algorithm is reduced by 257.106, and the mean absolute error decreased by 145. 675, the mean absolute percentage error dropped by 5. 655%, proving that the proposed hybrid algorithm has higher prediction accuracy. The experiment results based on the passenger flow data of Nanjing metro station show that compared to a single ARIMA model, the proposed ARIMA Kalman filtering hybrid algorithm reduces the root mean square error of the prediction results by 257.106, the average absolute error by 145.675, and the average absolute percentage error by 5.655%. It has been proven that the proposed hybrid algorithm has higher prediction accuracy.

By basing on the same physical model and treatment method, as used in our recent works [1, 2, 3, 4, 5], we will investigate the critical impurity densities in the metal-insulator transition (MIT), obtained in three n(p)-type degenerate [GaAs1−xTex,GaAs1−xTex,GaAs1−xTex]- crystalline alloys, 0≤x≤1, being due to the effects of the size of donor (acceptor) d(a)-radius, rd(a), the x-Ge concentration, and finally the high d(a)-density, N, assuming that all the impurities are ionized even at T=0 K. In such n(p)-type degenerate crystalline alloys, we will determine:(i)-the critical impurity densities NCDn(CDp)(rd(a),x) in the MIT, as that given in Eq. (10), by using an empirical Mott parameter
基于我们最近的研究成果[1, 2, 3, 4, 5]中使用的相同物理模型和处理方法，我们将研究在三种 n(p) 型退化[GaAs1-xTex,GaAs1-xTex,GaAs1-xTex]晶体合金（0≤x≤1）中获得的金属-绝缘体转变（MIT）临界杂质密度、GaAs1-xTex、GaAs1-xTex]- 晶体合金（0≤x≤1）中得到的临界杂质密度，这是由于供体（受体）d(a)半径 rd(a)、x-Ge 浓度以及高 d(a)-density N 的影响造成的。在这种 n（p）型退化结晶合金中，我们将通过使用经验莫特参数来确定：(i) MIT 中的临界杂质密度 NCDn（CDp）（rd（a），x），如公式 (10) 所示

PVT analysis is important for field-wide optimization and development. This is because we must understand the fluid's overall behavior from the reservoir to the production and processing facilities, and ultimately to the refinery. Modern computer software that uses equation of state (EOS) models to simulate experiments and illustrate fluid phase characteristics has contributed to its growth as a distinct field of study. To find the operating parameters that will maximize the surface liquid content and prolong the production plateau duration at the lowest feasible cost, PVT simulations are run. These simulations employ laboratory-derived data to fine-tune the EOS models, with the outcomes being integrated into reservoir simulation and research. The quality of the data is crucial to getting a good match between EOS and laboratory data, and for retrograde gas condensates, this can be particularly difficult because of their complex phase behavior. When utilized in reservoir simulations, an inadequate match leads to computational mistakes and unrepresentative findings, endangering the reservoir management decisions that depend on it.
PVT 分析对于整个油田的优化和开发非常重要。这是因为我们必须了解流体从储层到生产和加工设施，最终到炼油厂的整体行为。现代计算机软件使用状态方程（EOS）模型来模拟实验并说明流体相位特征，这促使其发展成为一个独特的研究领域。为了找到能以最低可行成本获得最大表面液体含量并延长生产高原持续时间的操作参数，需要进行 PVT 模拟。这些模拟利用实验室数据对 EOS 模型进行微调，并将结果纳入储层模拟和研究中。数据的质量对于 EOS 与实验室数据的良好匹配至关重要，而对于逆行气体凝析物来说，由于其复杂的相态行为，这一点尤为困难。在储层模拟中使用时，不适当的匹配会导致计算错误和不具代表性的结果，从而危及储层管理决策。
