No full textRepresenting Symbolic Controllers with Deep Neural Networks
No full textController synthesis techniques based on symbolic models or discrete abstractions are becoming increasingly attractive as they allow for synthesizing correct-by-design controllers of general nonlinear systems under complex behavioral requirements. However, its immense size as the consequence of the state-space explosion prohibits the approach to be widely used in real-life applications. The explosion of state space is mainly caused by the discretization in the abstraction step, and the redundancy of control inputs resulted in from the synthesis. Compression methods and determinization techniques have been developed to tackle the size problem of the resulting controller. Neural networks capabilities at approximating function and substituting look-up tables in broad applications, such as flight-critical system and deep reinforcement learning, motivate us to suggest utilizing neural networks as an alternative approach to represent the controller. In this work, the evaluation of the capability of neural networks as a viable approach to store a symbolic controller is presented. We present the utilization of neural networks to store deterministic controllers. We also propose a determinization technique based on the multiclass classification task in neural networks to determinize the controller. Additionally, we employ neural networks to store non-deterministic controllers by preserving the redundancy of the control inputs. Comparisons between binary decision diagrams (BDDs) and neural networks as compact representations of symbolic controllers are performed. Results show that neural networks are able to represent symbolic controllers in a more compact way compared to BDDs considering the size overhead produced by the CUDD package as its manipulation library.Electrical Engineering | Embedded System

In the sport of volleyball, more emphasis is placed on jumping rather than hitting, which must be performed quickly and powerfully. One of the key factors for achieving fast and powerful jumps is power training. Therefore, this study aims to examine the effect of the circuit training method on improving leg muscle power in volleyball athletes. An experimental method with a One-Group Pretest-Posttest Design was used in this study. The sample consisted of 8 female volleyball athletes (aged 12–17 years) selected using a total sampling technique from the entire population. The research instrument used was the Vertical Jump test, conducted twice—before and after the treatment. The athletes participated in a circuit training program for 16 sessions. A t-test using SPSS version 25 was employed for data analysis. Based on data processing and analysis, it was found that the circuit training method had a significant impact on improving leg muscle power in volleyball athletes. The circuit training method proved to be more effective and efficient in enhancing the leg muscle power of volleyball athletes.

The process of coal briquette through several phases. smashing the coal, coal dust mixing with tapioca as adhesive, and printing briquette coal. In general, the operation of the machine is still printing briquette coal operator manually where the operators pull down the lever with the hand or press it with foot. Because the quality of printing results that are less, the author bas some initiatives to improve the performance of these tools. Improvements to this tool is to make the calculation of the force of pressure, to create the framework more economical, to improve the printing of briquette, which once printing can produce 7 briquettes with each briquette have 30gram of weight, add the fixture, and improve the performance with using a hydraulics system. Results that obtained from the calculation of the force of pressure to print briquette of coal which have 25,223.9 N, with the specification of cylinder actuator as follows: Dpiston = 0.08 m, 0.025 m = Drod, Stroke = 0.06 m, maximum pressure = 98 bar. After that, was found that the pressure on the planning of cylinder which have 5,8x10pangkat5 N/m2 , capacity of pumps 2,81x10pangkat -5 m3/s and 225 Watt motor power
Peran Dan Tanggung Jawab Notaris Dalam Pembuatan Akta Terkait Pengambilalihan Agunan (Ayda) Sebagai Alternatif Penyelesaian Kredit Macet (Studi Kasus Pada Bank M Di Palembang)
No full textThis study discusses the role and the responsibility of a notary in making a deed related to the takeover of collateral (AYDA) as an alternative settlement of bad loans. Banks in channeling credit certainly need a notary as a bank partner who plays a role in making credit-related deeds. One of the settlements of bad loans at banks is by taking over collateral (AYDA), which is an asset obtained by the bank either through auction or outside the auction from the owner of the collateral, if the owner of the collateral/debtor is negligent in fulfilling his obligations. However, the implementation of AYDA often causes problems in settlement because the collateral is non-marketable, so that in the process of selling the collateral the bank has difficulty in disbursing it. The problems raised by the author are regarding the implementation of the settlement of bad loans at banks through the takeover of debtor\u27s collateral (AYDA); and the role and responsibilities of the Notary in making the deed related to the takeover of the debtor\u27s collateral. To answer this problem, a normative juridical legal research method with an explanatory typology is used. The data analysis was carried out qualitatively. The results showed that in the settlement of bad loans, the bank made an offer in the form of paying off all debtor\u27s debts, the debtor sold the collateral himself during the agreed time period or took over the credit to another bank, if the offer did not find results, the bank had to do AYDA. In the case of collateral that is difficult to disburse and cannot cover all of the debtor\u27s debt, the bank seeks to add additional collateral and make quick sales. Notaries as bank partners are responsible for the risks that arise in the deed they make. Therefore, a notary must be careful and uphold his professional ethics so as not to deviate from his authority

Structural Condition Assessment of a Log Bridge Under Heavy Traffic Load: Case Study 105 Tons Gas Engine Delivery in Central Borneo Project
No full textHeavy equipment transportation has become the biggest challenge in the implementation of a powerplant project in Central Borneo, Indonesia. The road structure composition was subgrade only, and a simple log bridge only connected several river crossings. One of the longest bridges was Palili Bridge, with a 29-m span. The existing Palili bridge was used for logging trucks with operation load 50–60 ton. While the heaviest equipment in the powerplant project is a Gas Engine with a weight of 105 tons, the structural modification shall be done. The log girder span was modified to be 18.00 m so that a couple of 5.50 m cantilever log abutment was constructed. Also, the main span and abutment improvement were conducted to resist 105 tons of load. The objectives of this research were to investigate the structural performance of the strengthened Palili Bridge under 105 tons of vehicle load with the safety criteria. In the structural investigation, direct loading test under static and dynamic load was conducted. Bridge displacement was monitored at half and a quarter of span. Furthermore, a numerical analysis of the Palili Bridge was conducted by using SAP2000 software to verify the testing result. As the direct loading test result, both static and dynamic fulfilled the corresponded regulation. Based on the log girder span displacement monitoring, and the numerical analysis result, the bridge could resist the loads with safety factor 3.57 on the main span and 2.46 on the cantilever abutment. The computed maximum displacements considering composite action were 7.72 and 8.79 mm for static and dynamic load, respectively, less than the limit of 40.28 mm (L/360). Based on the result, the design and concept of the log bridge were proved to be feasible and could be applied in any other similar site condition. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd
