Role of Co-Working Spaces’ Services in Entrepreneurs Growth in Upper Egypt: The Case of Step Co-Working Space

Co-working spaces are a new concept in Upper Egypt; Step co-working space is the first co-working space in Assiut governorate. Through co-working spaces services and facilities, this paper developed a new operationalization of the entrepreneurs’ growth. This research design resulting conceptual framework proposes that certain combinations of cost-sharing concepts, entrepreneurial awareness, NGO support, Mentoring, and Networking activities would increase the expectation of challenging entrepreneurial growth in Upper Egypt.A survey of unstructured interview and questionnaire used two data collection methods as a research instrument and was applied to the owner managers of Egyptian enterprises. The purpose of this paper is to investigate the relationship between entrepreneurs’ growth expectations and cost sharing, awareness, NGOs support, Mentoring, Networking, gender, facilities, and unemployment in Upper Egypt

The New Era of Digital Transformation and COVID-19 Effect on The Employment in Mobile Operators in Egypt

A fear from Technological Advances mainly automation and artificial intelligence (AI) has been raised since the beginning of the 21st century, that machines will eliminate human beings performing certain tasks. Several models were developed to measure the effect of the Automation & AI on the employment and was applied on several countries. The first model was developed by Carl Benedikt Frey and Michael A. Osborne was called An Occupation-Based Approach, 2013. In which they define several tasks and call it “Engineering-Bottlenecks”. Katharina Dengler, Britta Matthes and Wiebke Paulus, 2014 made The Occupational Tasks model in which they use the assignment of activities explained by Alexandra Spitz-Oener and categorize the non-automatable tasks as: analytical non-routine tasks, interactive non-routine tasks. The last model was A-Task Based Approach by Melanie Arntz, Terry Gregory, 2016 in which they argue that FO Model Ignore that, the occupations consist of many tasks, part of them can be automated and another part cannot be. These models were applied on the level of the countries but not on corporate levels.The purpose of this paper is to combine the above three models and applying them on the Mobile operators in Egypt to determine the effect of Automation and AI on the Employment there, taking into consideration the incremental risk from COVID-19 which influenced the humanity.The conclusion of this research is that 41% of the staff working in the Technology field on the mobile operators, their jobs are subject to automation and COVID-19 will make an incremental Risk of 8%, due to creation of efficiency on performing the un-automatable tasks from home through digital platforms

An expectation-based editing interface for OpenStreetMap

Building an open-source world map was one of the main reasons OpenStreetMap (OSM) was founded. Over 1.3 million contributors participate in editing the the world map collaboratively. Unfortunately, there is no support or any assistive technology solutions that helps blind and visually impaired users to blend into the OSM community. The aim of this thesis is to provide them with an assistive OSM editing application with an adaptive user interface that matches their needs. A mobile application for OSM editing was developed with an assistive recommendation system that helps predicting changes users might need to commit. The thesis describes in details the application design, decisions made, workflow and modularity

Elsafty_RBCs_for_Classification dataset

The Elsafty_RBCs_for_Classification dataset is systematically structured into three primary folders: "Cropped images”, "Masks”, and "Segmented images”. Within each of these primary folders, there are nine subfolders, meticulously dedicated to each RBCs class, encompassing the following counts of cells: "Angled cells: 24,187", "Borderline ovalocytes: 35,540”, "Burr cells: 8,948”, "Fragmented RBCs: 7,186”, "Ovalocytes: 55,073”, "Rounded RBCs: 46,338”, "Teardrops: 16,298”, "Three-overlapping RBCs: 15,577”, and "Two-overlapping RBCs: 31,360”. Each of the total 240,507 cells is represented by its own cropped image, mask, and segmented image. Samples for every class were collected from each slide/smear. The naming scheme for the cropped image, mask, and segmented image of every cell adheres to a consistent format, starting with the slide/smear number, followed by the unique patch/field number, and concluding with the (XYWH) coordination on the patch. All these images are conveniently stored in the lossless ".PNG" format.The presence of fragmented RBCs or teardrop-shaped RBCs is medically significant as it is commonly associated with serious medical conditions. Fragmented RBCs are defined as RBCs that are smaller than half the average normal/rounded RBCs size and/or irregularly shaped fragments with sharp, angular, or jagged edges. Identifying these cells is the most reliable indicator to confirm the diagnosis of diseases such as hemolytic anemias, thrombotic thrombocytopenic purpura (TTP), and disseminated intravascular coagulation (DIC). However, reporting fragmented RBCs in TTP and DIC can be a challenge due to their infrequency in hematology labs; furthermore, the cutoff for significant presence in these two serious diseases is just above 1–1.5% of the total RBCs, increasing the risk of overlooking them. Crucially, in cases of critical thrombocytopenia where the platelet count is less than 20 K/µL, platelet transfusion may be necessary, but this intervention can be life-threatening in TTP and DIC. Therefore, identifying and counting fragmented RBCs could be critical for the accurate diagnosis and management of patients with associated medical conditions.Increased teardrop-shaped RBCs above 2–4% in adults can be indicative of bone marrow fibrosis caused by bone marrow cancers, and in non-cancerous conditions, rushed erythropoiesis/production of blood to compensate for severe anemia is the differential diagnosis. Currently, manual or DL-based visual examination is the only way to identify teardrop-shaped RBCs. It is essential to differentiate between true teardrop-shaped RBCs, which have a single blunt protrusion, and false ones that have sharp surface projections without necks or have more than one blunt protrusion. Mechanical stress during blood smear preparation often leads to the formation of false teardrop shapes, primarily at the outer edges of the blood film.Ovalocytes are a type of RBCs that have an abnormal oval shape. The presence of ovalocytes exceeding 5–10% of the total RBCs is associated with almost all types of anemia or erythrocytosis. They may display elongation and/or a pear shape, but without any blunt or sharp surface protrusions. Occasionally, they can also appear in normal blood smears due to mechanical deformation during preparation, though at a low frequency.The burr cells have uneven surfaces with several small notches and protrusions. Likewise, no technological substitute currently exists for the visual recognition of burr cells, which tend to elevate under conditions of dehydration, such as in cases of renal failure or dehydrated neonates. Alternatively, in situations lacking medical justification, the presence of burr cells may arise due to the extended drying of smears during the manual staining procedure.</p

Investigation of Likelihood of Cracking in Reinforced Concrete Bridge Decks

One of the biggest problems affecting bridges is the transverse cracking and deterioration of concrete bridge decks. The causes of early age cracking are primarily attributed to plastic shrinkage, temperature effects, autogenous shrinkage, and drying shrinkage. The cracks can be influenced by material characteristics, casting sequence, formwork, climate conditions, geometry, and time dependent factors. The cracking of bridge decks not only creates unsightly aesthetic condition but also greatly reduces durability. It leads to a loss of functionality, loss of stiffness, and ultimately loss of structural safety. This investigation consists of field, laboratory, and analytical phases. The experimental and field testing investigate the early age transverse cracking of bridge decks and evaluate the use of sealant materials. The research identifies suitable materials, for crack sealing, with an ability to span cracks of various widths and to achieve performance criteria such as penetration depth, bond strength, and elongation. This paper also analytically examines the effect of a wide range of parameters on the development of cracking such as the number of spans, the span length, girder spacing, deck thickness, concrete compressive strength, dead load, hydration, temperature, shrinkage, and creep. The importance of each parameter is identified and then evaluated. Also, the AASHTO Standard Specification limits live-load deflections to L/800 for ordinary bridges and L/1000 for bridges in urban areas that are subject to pedestrian use. The deflection is found to be an important parameter to affect cracking. A set of recommendations to limit the transverse deck cracks in bridge decks is also presented. © 2013 The Author(s)

Theoretical and experimental study of a cross-flow induced-draft cooling tower

The main objective of this study is to find a proper solution for the cross-flow water cooling tower problem, also to find an empirical correlation's controlling heat and mass transfer coefficients as functions of inlet parameters to the tower. This is achieved by constructing an experimental rig and a computer program. The computer simulation solves the problem numerically. The apparatus used in this study comprises a cross-flow cooling tower. From the results obtained, the 'characteristic curve' of cross-flow cooling towers was constructed. This curve is very helpful for designers in order to find the actual value of the number of transfer units, if the values of inlet water temperature or inlet air wet bulb temperature are changed. Also an empirical correlation was conducted to obtain the required number of transfer units of the tower in hot water operation. Another correlation was found to obtain the effectiveness in the wet bulb operation

There is a huge investment in our infrastructure that is vital to our social and economic life. However, the aging and deterioration of the structures require implementing a damage detection system to monitor their structural integrity. In this study, a new alarming system was developed as part of a structural health monitoring system and installed in a scaled-down structure models. The designed system incorporated microprocessors, wireless communication, transducer, and cellular transmission that allow remote monitoring. The developed system facilitates continuous monitoring process of any part of structures and controlled remotely from any location. The system was equipped with data processing subsystem that detects structural behavior irregularity, defects, and potential failures. The system was tested using Lin-ear Variable Differential Transformer (LVDT) for deflections and using strain gages to measure the developed axial and flexural strains in different structural models. Filtering algorithm was used to filter graphs and the data gathered in each loading stage was averaged and plotted to show the abrupt change in the values. The filtering system helps the alarming system to have a clear prediction of possible irregularities. The developed system provides the desired features of low cost, low power, small size, flexibility and easy implementation, remote accessing, early detection of problems, and simplified representation of the results

Theory-based approaches and microstructural analysis to evaluate the service life-retention of stressed carbon fiber composite strands for concrete bridge applications

Prestressed concrete girders and piles with steel strands are used in construction of bridges in North America, due to their economy of design, fabrication, and installation. However, they are often exposed to harsh environments, which results in rapid degradation. Therefore, carbon fiber reinforced polymer (CFRP) tendons have successfully been introduced as prestressing reinforcement for pile applications. This paper presents a study on the physical characterization, microstructural analysis, and durability performance of unstressed and stressed carbon-fiber composite cables (CFCCs) for prestressing applications. This is achieved through testing 120 CFCC specimens, subjected to stress levels of about 40% and 65% of their guaranteed strength, and 51 specimens without sustained load under tension. Moreover, prediction models were introduced to assess the long-term performance and retentions of CFCC strands. The models included Arrhenius model, Fick\u27s law, Fib Bulletin (40) model, and a developed approach that incorporates the effects of temperature, design life, and relative humidity of exposure into the environmental reduction factor. Based on the predication model, the tensile strength retention (CE) for CFCC strands, is predicted to retain over 0.95 and 0.84 of ultimate tensile strength for a relative humidity (RH) \u3c 90% and a moisture saturated environment (RH = 100%), respectively, after 100 years of service life with elevated temperature and sustained load
