1. A COMPUTATIONAL VIEW AT SOFTWARE PRODUCTION

Authors: Ronald Kaschek

Abstract: Computers are machines for the approximate execution of mathematical operations. By using appropriate software, computers can be used to help solve practical problems. The process of producing software is a quite complicated one and surprisingly is usually not discussed in terms of figuring out the Mathematical model that finally is going to be evaluated by the computer. In this paper we identify the software process stage, in which the Mathematical model is produced. We also discuss the Mathematical concept of quantity, how to measure quantities and Mathematical model

2. KNOWLEDGE CLEANSING IN POST-ACQUISITION INTEGRATION

Authors: Dongcheol Heo

Abstract: Based on four post-acquisition experiences of one global medical system manufacturing firm, this study examines how knowledge cleansing occurs in post-acquisition integration. The two factors are important in explaining cleansing after the acquisition: the perceived strategic value of acquired knowledge and the target firm’s certainty level on protecting its knowledge. The case finding shows four cases are divided into two highcleansing and two low-cleansing cases. Both the combination of high value of knowledge and high certainty of knowledge protection and the combination of low value of knowledge and low certainty of knowledge protection turned out as high cleansing. In contrast, high-low and low-high combinations of the two factors resulted in low cleansing. Based on this categorization, the study develops the process model of knowledge cleansing in post-acquisition integration. This study sheds new light on the knowledge management study in post acquisitio integration.

3. DESIGN AND IMPLEMENTATION OF A NON-CONTACT DETECTION SENSOR WITH PARASITIC CAPACITANCE AND PULL-UP RESISTANCE

Authors: HAK-HUI CHOI , Joon-Hyuk Choi

Abstract: This paper designs and implements a capacitive non-contact detection sensor using parasitic capacitance and pullup resistance. The proposed sensor replaces the peripheral components of existing sensors with the parasitic capacitance and pull-up resistance inherent in the Arduino, thereby reducing the sensor design cost. It also provides stable output by using experimentally designed compensation coefficients and filters. Additionally, the measured sensor values are monitored via a mobile application, and the performance of the implemented sensor is evaluated by comparing the measured values with the actual capacitor values.

4. MEASURING THE DISTORTION FORCE OVER TIME BY EXPERIMENTAL METHODOLOGY RESULTING IN MAINTAINING AND IMPROVING THE STUMBLE RECOVERY ON A HUMANOID ROBOT

Authors: ASHOK KUMAR RAMADOSS

Abstract: Humanoid robots movement without lying down in ground is of major importance This thesis focuses on the hip-ankle strategy as a method to maintain balance when subjected to a large disturbance. This strategy is characterised by a large rotation of the hip joint which repositions the Centre of Mass (CoM). The hip-ankle strategy is compared to the ankle strategy which locks the hip joint and compensates for a disturbance by applying ankle torque. Various hip-ankle strategy controllers have been presented in literature of which three im- plementations on humanoid robots are known. However, none of the research provided ex- perimental evidence that a humanoid robot can withstand larger disturbances by using the hip- ankle strategy compared to the ankle strategy.

5. CAMERA AI BASED REPLENISHMENT SYSTEM

Authors: Sachin More , Gajendra Deshpande

Abstract: The disruption of the worldwide supply chain and logistics distribution caused by COVID-19 is well known, and it presented a new set of commercial issues The issue of inaccurate inventory is causing retailers to struggle. Inventory is a crucial component in creating the proper order demand and plays a significant part in assessing shop demand. The potential for a camera AI-based inventory management and replenishment system is enormous, notwithstanding the usage of more conventional techniques like cycle counts and third-party inventory services. Since some slow moving items make it difficult to interpret the product sales pattern, a quantity of machine learning models consumed remained employed to determine theoretical inventory based on previous transactional data (time series). However, these models have not been able to address the issue of inventory inaccuracy. Although slow-moving items may not account for a large portion of sales (the80-20 rule), they may assist draw people

6. BEHAVIOUR OF A ROCK MASS UNDER ACTION OF STATIC AND SEISMIC LOADS

Authors: Javier O. Morandi , Ricardo J. Uliarte , Amelia E. Carmona , Roberto C. Muñoz

Abstract: The beginning of a research work that will study the response of the foundation structure of a Radio Telescope (RT) in the town of Barreal, 2500m above sea, in San Juan province, the most dangerous seismic zone of the Argentine Republic, is presented. The RT has a satellite dish of 40m in diameter and 1200 tons of its own weight. It is founded in a Direct Superficial way by means of a Square Base of Reinforced Concrete of 27m on each side. All previous studies on the rock mass and their geomechanical properties have been carried out. An auscultation system has been installed in the Rock mass that will measure accelerations, pressures and deformations. A triaxial accelerometer has been installed, pressure sensors at three points uniformly distributed on the support surface, with their corresponding extensometers that measure displacements at depths equal to B, 0.5B and 0.25B. One of the pressure cells includes an inclinometer. The installation of the RT is expected to take place during

7. FINITE ELEMENT SIMULATION OF ULTRA-FINE STAINLESS STEEL WIRES:MULTISCALE ANALYSIS USING CRYSTAL PLASTICITY

Authors: Naoki Maekawa , Ken-ichi Saitoh

Abstract: By using finite element method (FEM), we investigate hardening behavior during wiredrawing of ultra-fine stainless steel. To incorporate microstructural changes in polycrystalline grains of austenite stainless steel, slip systems are actually placed in cubic crystal lattice, and a crystal plasticity (CP) FEM analysis is performed. Some parameters (for example, initial hardening rates, and etc.) required in CP-FEM of stainless steel are missing and they are supposed to be difficult to obtain experimentally. Therefore, a series of uni-axial tensile simulations are conducted to determine those parameters which reproduce the experiment. Then, we performed CP-FEM simulations under multi-axial stress conditions corresponding to the wiredrawing condition to investigate the distribution of equivalent strain and stress. The results show that stress and strain tend to decrease towards the surface region, which suggests that hardening b

8. INVESTIGATION ON SUSTAINABLE BUSINESS GROWTH OF EMERGING CONTRACTORS IN AFRICA: A CASE STUDY FOR ETHEKWINI MUNICIPALITY, SOUTH AFRICA

Authors: Oscar Kunene , Prof Kin Sibanda

Abstract: Small and Medium Enterprises (SMEs) in the construction industry play a pivotal role in addressing worldwide chronic challenges such as unemployment, inequality and poverty. In South Africa, small to medium emerging contractors in the construction sector experience a substantial failure rate despite their notable socio-economic impacts. Thus, emerging contractors have not yielded any significant growth in the previous years. Numerous contracting businesses have closed, leading their owners to pursue opportunities in different sectors. This pattern emphasizes the ongoing difficulties that emerging contractors in not only South Africa but also other African countries like Kenya, Nigeria, and Ghana are facing. To address these challenges, the South African government has put in place different policies and programs to help small contractors thrive. Still, advancement is sluggish, as the rate of failure continues to be alarmingly high.

9. FUZZY TIDF CONTROLLER DESIGN FOR DEREGULATED AGC SYSTEMS USING MOTH-FLAME OPTIMIZATION

Authors: Tulasichandra Sekhar Gorripotu , G Raam Dheep , K. Alfoni Jose

Abstract: This paper deals with the performance of two control area within a deregulated multi source power system. Both the two areas includes thermal and gas units. The proposed controller is cascade combination of the fuzzy controller and the tilt integral derivative controller with filter (fuzzy TIDF). The controller's parameters are optimized using an advanced Moth Flame Optimization Algorithm (MFOA). This work highlights the superior performance of fuzzy TIDF controller in comparison to PID and TID controllers. This assessment is based on the observation of dynamic responses across different controller configurations. This particular study examines the system’s behaviour under poolco based and bilateral scenarios. In summary, this paper presents a new Fuzzy+TIDF controller optimized using a MFOA within a two-area system operating in a deregulated context to mitigate the frequencies and tie-line power.

10. IMPACTS OF FUTURE LAND USE ON VEGETATION CO2 FLUXES OVER MADRID, SPAIN

Authors: ROBERTO SAN JOSE , Juan L. Perez-Camanyo

Abstract: Biogenic CO2 fluxes are influenced by temperature, radiation, and vegetation, which are represented by different land use types and affect CO2 concentrations. High-resolution meteorological and land-use data were generated to model these factors. Vegetation indices were derived from the land use data and used to estimate biogenic emissions. These calculations were applied within three nested computational domains centred on Madrid (Spain). To assess the impacts of future land use on biogenic CO2 emission fluxes, two simulations were conducted: R1, representing the socio-economic scenario of 2018 (baseline year), and R2, reflecting future socio-economic scenarios. The impacts were calculated by comparing the differences between R2 and R1. The research covered four climate and socio-economic scenarios: SSP126, SSP245, SSP370, and SSP585. This study is part of the EU-funded DISTENDER project, which aims to develop a methodological framework to integrate climate adaptation and mit
