For more than a century, forecasting models have been crucial in a variety of fields. Models can offer the most accurate forecasting outcomes if error terms are normally distributed. Finding a good statistical model for time series predicting imports in Malaysia is the main target of this study. The decision made during this study mostly addresses the unrestricted error correction model (UECM), and composite model (Combined regression—ARIMA). The imports of Malaysia from the first quarter of 1991 to the third quarter of 2022 are employed in this study’s quarterly time series data. The forecasting outcomes of the current study demonstrated that the composite model offered more probabilistic data, which improved forecasting the volume of Malaysia’s imports. The composite model, and the UECM model in this study are linear models based on responses to Malaysia’s imports. Future studies might compare the performance of linear and nonlinear models in forecasting.

This paper deals with the modeling, analysis and optimization of a specific kind of real industrial problems. This class of problems is known in the literature as Cyclic hoist Scheduling Problem （chSP）. In such class of problems, several jobs have to flow through a production line according to an ordered bath sequence. The chSPs appear in the manufacturing facilities to achieve a mass production and to search a repetitive sequence of moves for the hoist. In this paper, we develop P-Temporal Petri Net models to represent the behavior and validate certain qualitative properties of the basic production line. Afterward, complex configurations of the production line are modeled and their properties such as reachability of desired functioning （cyclic operation）, deadlock-free, resource sharing and management are checked and validated. A mathematical analysis and a simulation study of all proposed Petri net models are carried out using mathematical fundaments of Petri nets and a Visual Object Net ＋＋ tool. The second part of the paper deals with the development of a mixed integer linear programming models to optimize processing of each line configuration. Optimal manufacturing plans of the studied system with cyclic processing sequences are defined and the feasibility of optimal cyclic scheduling of each configuration is proved.

This paper deals with an optimization approach to design a cable driven parallel robot intended for upper limb rehabilitation tasks. The cable driven parallel robots have characteristics that make them best candidate for rehabilitation exercise purposes such as large workspace, re-configurable architecture, portability and cost effectiveness. here, both the cable tensions that are needed to move a wristband as well as the workspace need to be carefully optimized for fulfilling the prescribed operation tasks. A specific case of study is addressed in this work by referring to LA RM wire driven exercising device (LAWEX), which is applied to upper limbs exercises. To that end, a motion capture system is used to collect quantitative data on the prescribed workspace of a human upper limb. A specific optimization problem is settled up for considering combining two optimization goals, namely, the smallest robot size reaching a prescribed workspace and the minimum cable tension distributions. A sequence of optimization steps is defined using Genetic Algorithms (GAs) applied to LAWEX robot. The proposed objective function is based on a mathematical formulation of the power of a point with respect to bounding surfaces in combination with a performance index to show the distributions of the minimum cable tensions.

Introduction: Late pregnancies are considered a public health problem linked to maternal mortality due to their complications. These risks, which worsen with maternal age, should be better known and taken into account in monitoring these pregnancies. Objective: To evaluate the impact of age on the prevalence of obstetric and neonatal complications among parturients of 40 years old and over. Methodology: This was an 11-year retrospective analytical case control study from January 1, 2007 to December 31, 2017. The study population was female patients of 40 years old or older for cases and female patients younger than 40 years of control case. Results: In total, we collected 640 cases of parturients of 40 years old and over out of a total of 84,234 deliveries during the study period;i.e. a frequency of 0.76%. Spontaneous abortion increased in patients of 40 and over with 8.28%. hypertension and diabetes were higher of women of 40 and over, 52.65%. Concerning the method of admission: 55% of parturients of 40 and over were referrals. Incidents occurring among women of 40 and over were more pronounced than in control cases. Complications during vaginal delivery, cervical tear, perineal tear, uterine dehiscence and uterine rupture are high in our cases, i.e. 11.88%;3.59%;2.19%;2.66. During our study, depending on the type of delivery, the cesarean rate was much higher among women of 40 and over than among control cases, i.e. 54.22% versus 12.24%. hemorrhages in the 3rd trimester were the main indications for cesarean section. hemorrhages in the 3rd trimester were more frequent with women of 40 and over, i.e. 10.47%;5.94% versus 1.74% and 0.42%. As for the different types of malformations in parturients, women under 40 years old fetal malformations were absent in 92.29%, on the other hand they were more frequent in patients with 40 years and over, i.e. a normal frequency of 36.72%. Conclusion: Pregnancy at a late age exposes the elderly patient and the newborn to several ri

In this work, a systematic approach is presented to obtain the input-output equations of a single loop 4-bar spatial mechanisms. The dialytic method along with Denavit-hartenberg parameters can be used to obtain these equations efficiently. A genetic algorithm （GA） has been used to solve the problem of spatial mechanisms synthesis. Two types of mechanisms, e.g., RSCR and RSPC （R： revolute; S： spherical; C： cylindrical; P： prismatic）, have illustrated the application of the GA to solve the problem of function generation and path generation. In some cases, the GA method becomes trapped in a local minimum. A combined GA-fuzzy logic （GA-FL） method is then used to improve the final result. The results show that GAs, combined with an adequate description of the mechanism, are well suited for spatial mechanism synthesis problems and have neither difficulties inherent to the choice of the initial feasible guess, nor a problem of convergence, as it is the case for deterministic methods.
