Falling Standard of education in Pakistan: Who will tie the bell?
Authors: Afzal Muhammad , Qadir Fazli
Published: August 2022

The paper investigated and analysed the various factors assumed to be responsible for falling quality of education and the necessary data were collected from university students whom were asked relevant questions. Students expressed dissatisfaction on the semester system and BS program. BS program has killed the students because they are bogged down in the vicious circle of plethora of courses which not only affect their health but also their academic performance. MPhil and PhD admissions are reduced to minimum in the light of demand and supply to avert future problems.The most deplorable aspect is TTS which is supposed to have done more harm and damage to the national exchequer than alleged good. Lecturers in universities enjoy the lucrative BPS-18 scale while doctors, engineers, civil servants are inducted in BPS-17.   Step-motherly treatment of other civil servants will certainly add to bad blood. TTS and induction in BPS-18 as lecturer must be stopped once for all. Lack of job opportunities and rapid population growth are potential factors responsible for falling standard of education. When students are aware that their hard labour will not bear fruit, they lose interest in working hard. Social media has added fuel to the fire.

This is the motive of most people are interested in cultivating such fish; beside the selling price is relatively high, it also has increasing ramp of demand every year. In order to meet the increasing demand, the fish farms are in need of appropriate feed aiming for upgrading cat fish growing rate. Around Lhokseumawe region, despite of numerous tofu industries the dregs are still not well utilized. The waste of tofu industries, which is tofu dregs, functions as cat fish feed. Tofu dregs made cat fish feed has numbers of advantages, such as accelerating the fish growth until 17-18%. This is due to the coarse fiber protein contain to be 7.11%, fat 4.93% and BETN 44.50%. Beside its nutritional advantages as alternative cat fish feed raw material, tofu dregs as cat fish feed material should be examined in technical and financial aspects so that it is guaranteed to be implemented. Hence, in this research the feasibility study was conducted on technical aspects of processing solid tofu dregs to be cat fish feed by using BEP and PP analysis methods. According to Payback Period (PP) value, the business has three months and six days period of time in order to return the initial investment capital. The production rate in one months must be above 542 kg in order to avoid from being lost. With the existing production capacity (1.092 kg/month), the cat fish feed price must be above IDR 6.116/kg in order to cover all expenditure in the time period.

Pengaruh Clearance In Dan Out Terhadap Jumlah Kunjungan Kapal Yang Diageni Oleh PT Buana Lintas Lautan Jakarta
Authors: Lauren Lauren

Shipping is part of a very strategic marine transportation facility for the maritime world and is a vital means that supports the goals of national unity and integrity and realizes Indonesia's ideals as a world maritime axis and to support the Indonesian economic sector.

One of the shipping companies in Indonesia where I practice is PT. Buana Lintas Lautan Jakarta which was founded in 2005. Since its inception PT. Buana Lintas Lautan Jakarta is required to provide the best and maximum possible service to service users, because in the shipping world, service is prioritized, so that service users feel satisfied and have confidence in the management and transportation of their goods.

Clearance services in and out of ships is one type of service provided by the company to service users. To maintain the trust of service users who use ship agency services to the company, the service must be carried out briefly and smoothly without being constrained. short and smooth, without experiencing any obstacles. The clearance process for these agencies as a whole should be able to be done in less than 24 hours.

However, in the course of handling in and out clearance services, they often encounter several obstacles, including: preparation of complete ship clearance documents at PT. Ocean Crossings is not optimal, the information provided by the agent to the ship regarding the readiness of the ship, both in terms of documentation and physically when the ship arrives, is felt to be lacking, so that when the ship arrives the ship is not ready to do clearance. The lack of communication between agents and related agencies such as (Customs and Excise, KSOP, Immigration, Quarantine and Pelindo) also hampers ship clearance services so that it takes longer. So companies need to reduce clearance processing time so that the number of ships that the company agency can be more more and faster service.
Sequential Convex Programming Methods for Real-time Optimal Trajectory Planning in Autonomous Vehicle Racing
Authors: Scheffe Patrick , Kloock Maximilian , Henneken Theodor Mario , Alrifaee Bassam
Published: August 2022

Optimization problems for trajectory planning in autonomous vehicle racing are characterized by their nonlinearity and nonconvexity. Instead of solving these optimization problems, usually a convex approximation is solved instead to achieve a high update rate. We present a real-time-capable model predictive control (MPC) trajectory planner based on a nonlinear single-track vehicle model and Pacejka's magic tire formula for autonomous vehicle racing. After formulating the general nonconvex trajectory optimization problem, we form a convex approximation using sequential convex programming (SCP). The state of the art convexifies track constraints using sequential linearization (SL), which is a method of relaxing the constraints. Solutions to the relaxed optimization problem are not guaranteed to be feasible in the nonconvex optimization problem. We propose sequential convex restriction (SCR) as a method to convexify track constraints. SCR guarantees that resulting solutions are feasible in the nonconvex optimization problem. We show recursive feasibility of solutions to the restricted optimization problem. The MPC is evaluated on a scaled version of the Hockenheimring racing track in simulation. The results show that an MPC using SCR yields faster lap times than an MPC using SL, while still being real-time capable.
Resource Allocation for Joint Interference Management and Security Enhancement in Cellular-Connected Internet-of-Drones Networks
Authors: HASSAN MD ZOHEB , Kaddoum Georges , Akhrif Ouassima
Published: August 2022

Internet-of-drones (IoD) systems require enhanced data transmission security and efficient interference management to accommodate the rapidly growing drone-based and rate-intensive applications. This paper develops a novel resource allocation scheme to jointly manage interference and enhance the physical layer security  of  cellular-connected IoD networks in the presence of a multi-band eavesdropping drone. Our envisioned cellular-connected IoD network has multiple full-duplex cellular base stations (CBSs), where each CBS reserves an orthogonal cellular  radio resource block (RRB) for the aerial communication links. To efficiently utilize the cellular RRBs, each CBS is connected to a cluster of data transmitting drones using uplink  non-orthogonal multiple access (NOMA) scheme. In addition, all the CBSs simultaneously transmit  artificial noise signals to weaken the eavesdropper links.  A joint optimization problem, considering the transmit power allocation and clustering of the legitimate drones, and the jamming power allocation of the CBSs, is formulated to maximize the worst-case average sum-secrecy-rate of the  network. The joint optimization problem  is decomposed into  drone-clustering and power allocation sub-problems to obtain an efficient solution. A multi-agent reinforcement-learning framework is devised to solve the drone-clustering sub-problem.  Meanwhile, the transmit and jamming power allocation sub-problem is solved by employing fractional programming, successive convex approximation, and alternating optimization techniques. By iteratively solving these two sub-problems, a convergent resource allocation algorithm, namely, security and interference management with reinforcement-learning and NOMA (SIREN), is proposed.  The superiority of SIREN over several benchmark schemes is verified via extensive simulations. 
A recursive system identification inertia estimator for traditional and converter-interfaced generators
Authors: Gotti Davide , Ledesma Pablo , Amaris Hortensia
Published: August 2022

This paper proposes a method to estimate the inertia constant of synchronous generators (SGs) and the virtual inertia provided by converter-interfaced generators (CIGs). It can be applied when the system is under normal operating conditions or after power imbalance events. The algorithm is based on a recursive system identification approach and uses the active power and bus frequency measurements proceeding from phasor measurement units. The measurements are preprocessed to improve the estimation accuracy. Subsequently, a model-independent rotor speed estimator is used to compute rotor speed variations (or internal frequency variations, in the case of CIGs). Afterwards, a recursive least-square equation error formulation is implemented to compute the SG and CIG parameters in the z-domain, which are later converted into their respective counterparts in the s-domain. The method is applied to several generation devices in the IEEE 39-bus and IEEE 118-bus test systems, including traditional SGs and CIGs providing virtual inertia. Numerical results show the accuracy and the low computational burden of the proposed method.

Background: Glaucoma is a typical side effect of juvenile cataract surgery. According to various research, it seems to have a bimodal occurrence. In Bangladesh, these difficulties constitute a hardship. Objective: In this study our main aim is to evaluate the prevalence and Risk Factors of Glaucoma Following Pediatric Cataract Surgery with Primary Implantation in Tertiary Eye Hospital. Method: This cross-sectional study was carried out at tertiary eye hospital, Bangladesh from August 2021 to June 2022. Where a total of 200 children who underwent unilateral or bilateral cataract surgery with primary IOL implantation in the first year of their life. All eyes presenting with an isolated cataract or an anterior form of persistence of fetal vasculature not requiring posterior vitrectomy or a moderate microphthalmia allowing primary IOL implantation and with a follow-up of >1year were included in the study. Results: During the study, 70% were female and majority were belong to 7-12 years age group, 55%. According to Intraoperative, and Postoperative Characteristics of study group where bilateral cataract was seen in 45% cases followed by 49% cases were capsular bag, 37% cases were sulcus, 46% used trypan bag. Comparing the SG group to the group that did not develop glaucoma, follow-up time was longer (mean 7,5 vs 5.6 years, P<.001), age at surgery was lower (mean 4 vs 5.0 years; P¼.045), reintervention was more frequent (P<.001), and trypan blue was used more frequently (P¼.008). In univariate analysis, the following factors were significantly associated with an increased risk of SG: axial length<16.5 mm, bilateral cataract, perioperative use of trypan blue, additional surgical procedures, and younger age at surgery. Conclusion: We may infer that the risk of SG increases with time, and that SG appears to have a bimodal occurrence, with an estimated linear incidence rate each year. Follow-up should begin quickly after surgery and last for a long time, and clinicians ......

Background: Reduced level of serum zinc has been observed in patients with type 2 diabetes mellitus (T2DM). Objectives: Estimation of serum zinc level and HbA1c in newly detected T2DM. Materials and methods: This cross-sectional study encompassed 100 newly detected non-pregnant T2DM subjects diagnosed on basis of ADA 2015 criteria (n=100; age: 44.74±11.34 years, mean+SD; Sex: 56/44, M/F) from the department of Endocrinology, BSMMU consecutively. Study period was March, 2015 to April, 2016. Blood sample was collected for measurement of zinc and HbA1c. Height, weight, waist circumference, hypertension, dyslipidaemia, ischemic heart disease (IHD), cerebrovascular disease (CVD), retinopathy, neuropathy, nephropathy, serum creatinine were recorded as confounding variables. HbA1c was measured using the NGSP certified Bio-Rad D-10TM Hemoglobin A1C Program while Zinc by using Atomic Absorption Spectrometric Analysis. Result: There was no statistically significant difference for zinc level in gender groups (M vs. F: 0.91±0.02 vs. 0.88±0.02 mg/L, p= 0.580; M±SEM), age groups (age <25 years: 0.89±0.82, 25 – 34 years: 0.90±0.03, 35 – 44 years: 0.90±0.32, 45 – 54 years: 0.91±0.03, and 55 years: 85±0.03 mg/L, M±SEM; F= 0.379, p= 0.823), body mass index (BMI) groups (BMI <25 vs. 25 kg/m2: 0.92±0.02vs. 87±0.02, p= 0.107), socioeconomic groups (low vs. middle vs. high socioeconomic status: 0.90±0.02 vs. 0.91±0.02 vs. 0.86±0.03 mg/L, M±SEM; F= 0.548, p= 0.580) as well as with and without family history of diabetes (0.90±0.01 vs. 0.89±0.02 mg/L, M±SEM; p= 0.705). Also zinc level was statistically similar among glycemic status groups (HbA1c < 6.5% vs. 6.5-9% vs. > 9%: 0.89±0.40 vs. 0.87±0.02 vs. 0.91±0.02 mg/L, F= 0.568, p= 0.569). Comparisons between groups with or without risk factors like: smoking (0.93±0.10 vs. 0.89±0.10 mg/L, p=0.724), hypertension (0.87±0.02 vs. 0.91±0.02 mg/L, p= 0.237), dyslipidemia (0.87±0.02 vs. 0.90±0.02 mg/L, p=0.393) and also co morbidities like: .......

Introduction: Parkinson's disease is a common progressive neurovegetative disorder, associated with rigidity, bradykinesia, tremor and postural instability; the conditions are not only limited to the extremities but can extend to the striated muscles within the upper airways and rib cage [1]. Anesthetic management in these patients can be difficult during the preoperative, intraoperative, and postoperative period. Objective: present the clinical case of an 81-year-old man diagnosed with Cholelithiasis, who underwent laparoscopic cholecystectomy at the Hospital General Enrique Garcés, who manifested an adverse event after extubation in the recovery room. Conclusion: upper airways present modifications in Parkinson's patients, this can difficult their management. The prevention of complications during this process will be largely due to the adequate pharmacological treatment for Parkinson's disease or its prompt introduction, and knowledge of the pharmacological effects of the different agents used during the anesthetic period.
