Systematization of the scientific background and approaches on preparing a marketing plan for e-marketing
organizations indicates that many companies, especially small companies, marketing their products via the Internet,
cannot develop a successful marketing plan. In turn, it could be solved through the use of AI techniques. The study
was conducted on a group of companies that market their products via the Internet in the Kingdom of Saudi Arabia.
To gain the research goal, this study was carried out in the following logical sequence: 1) developing the stratified
sample by collecting statistical information for 141 company in a variety of fields; 2) analyzing the data using SPSS;
3) predicting how AI could be used in preparing the marketing plan; 4) identifying the arrangement of the steps for
preparing the marketing plan in terms of the ability of AI techniques. The methodological tools of the study were
methods of the multiple regression analysis and the Friedman test. The study empirically confirms and theoretically
proves that AI contributes significantly in developing marketing plans through its great contribution to environmental
analysis and analysis of competitors' strategies and setting marketing goals. Besides, AI contributes to preparing the
budget and appreciating the marketing plan, to its evaluation and control. The author mentioned that AI provides
understanding and selecting target markets and sectors, targeting customers, and preparing appropriate marketing
mix strategies for each market sector. Therefore, the study provides recommendations to online organizations to

The smart safety Shoe: A new type of safety shoe that helps prevent lower back problems and opens the door to a new era of preventive safety footwear
No full textThe smart safety shoe is a concept safety shoe that has been in development as a collaboration between Allshoes safety footwear and TU Delft since 2020. Previous work on the shoe consisted of 2 graduation projects and a student course which resulted in the current concept of an injury preventing safety shoe focused on preventing lower back pain in the logistics sector. The shoe works by using pressure sensors and machine learning to detect unhealthy postures while its wearer has to lift various objects as part of their job (manual handling). This project focused on further developing the concept of the smart safety shoe and evaluating the prototypes from the last two projects. Previous projects provided two different pressure sensor layouts which are evaluated using a high-end pressure sensing insole. A manual handling experiment was set up and performed on 16 different participants from a lab and a warehouse. During testing participants were instructed to perform manual handling while holding 5 different postures. It was possible to train a machine learning model using the various pressure profiles gathered from the experiment. Using this model, the two sensor layouts from the previous projects were evaluated for their ability to detect the 5 predetermined postures. It was found that the latest layout outperformed the previous one and was therefore selected for further development of the smart safety shoe.The integration of various other sensors and actuators was evaluated, and the core functions of the shoe were defined with an indication towards future improvements of the smart safety shoe.The shoe has now been publicly presented by Allshoes and the goal is to have the product on the market by the end of 2025. In order for this to happen further prototyping is needed to create an improved machine learning model based on the selected sensor layout. The shoe shows promising responses from current safety shoe clients. When finally launched it will be part of a new type of protective equipment focused on prevention.Design for Interactio

Distyryl Derivatives as Corrosion Inhibitors for Carbon Steel in Acid Cleaning Process in Cooling Towers
No full textStresses at the Intersection of Sphere and Cylinder by a Variant Finite-Difference Method
No full textThe aim of this paper is the determination of stresses at the intersection of cylinder with the sphere using a variant finite-difference technique. Mesh lines are drawn on the cross section of the body which are roughly parallel and perpendicular to the boundary, and which the author calls natural meshes. Discretization of the governing differential equations must be carried out to reduce the continuous problem to a discrete problem, this discretization converts the problem into a set of linear simultaneous equations for the functions under consideration at a set of mesh points. The derivatives to be inserted in the governing equations and boundary conditions are found by writing Taylor series expansions at a point in terms of five neighboring points in the case where the point is an internal point (four for a boundary point). By an elimination process the derivatives can be eliminated for each point, and we are left with the unknown functions only.</jats:p
Basal interhemispheric approach for sellar and juxta-sellar lesions
No full textAbstract Background Sellar and juxta-sellar lesions represent a surgical challenge due their deep and complex relationships to surrounding important neurovascular structures. The basal interhemispheric (BIH) approach, as a midline approach, has an advantage over the lateral approaches as it allows for the safe removal of these challenging tumors. Aim To describe the technique of BIH approach in a prospective cohort of 17 patients with sellar and juxta-sellar lesions with different pathologies presented to Alexandria Main University and affiliated hospitals. As well as the clinical outcome and complications of this technique, these cases were followed up for a mean period of 20 weeks. Results Gross total resection was achieved in 9 cases (52.9%), subtotal resection was achieved in 5 cases (29.5%), while partial resection was carried out in 3 cases (17.6%). Visual status improved following surgery in 10 patients (58.8%), remained stationary in 5 patients (29.4%) and worsened in 2 cases. Post-operative shunt was needed in three cases, and severe water and electrolyte disturbance was recorded in 3 cases and pan-hypopituitarism in a single case. A single mortality was recorded, but it was due to pulmonary embolism and was not related to the approach. Conclusion BIH could be a panoramic safe approach that allows tumor removal from multiple corridors with identification of the regional anatomy of the tumor thus elaborating the surgical strategy for gross total tumor removal
Simulation and optimization model for electrical substation construction
No full text© 2018 The author(s). One of the most complex construction projects is electrical substations. Construction of electrical substation includes civil works and electromechanical works. The scope of civil works includes construction of several buildings divided into parallel and overlapped working phases that require variety of resources and are generally quite costly and consume a considerable amount of time. The construction industry is becoming increasingly competitive over the years, whereby the need to continuously find ways to improve construction performance. In order to address the aforementioned adversities, this paper takes the initial steps and presents simulation and optimization model for the execution processes of civil works for an electrical substation using a data base excel file for input data entry. The input data include bill of quantities, resources breakdown, maximum available resources, production rates, unit cost of resources and indirect cost. The model is built on Anylogic software using discrete event simulation method. The model is divided into three zones working in parallel to each other. Each zone includes a group of buildings related to the same construction area. Each zone-model describes the execution process of each building in the zone, the time consumed, percentage of utilization of equipment and manpower crews, amount of materials consumed, total direct and indirect cost. The model is then optimized to mainly minimize the project duration using a parameter variation experiment and a genetic code implemented using Anylogic platform. The models were then tested on a real case study in Egypt. The models prove efficiency by attaining a reduction in model time units between simulation and optimization experiments of 10.25% and reduction in total cost of 4.7%. An analysis to determine the effect of each resource on reduction in cost was presented. However, the model is limited to the scope of civil works, without considering the electromechanical works and the effect of risk factors on time and cost
Optimization-Based Proposed Solution for Water Shortage Problems: A Case Study in the Ismailia Canal, East Nile Delta, Egypt
No full textWater conflicts in transboundary watersheds are significantly exacerbated by insufficient freshwater sources and high water demands. Due to its increasing population and various development projects, as well as current and potential water shortages, Egypt is one of the most populated and impacted countries in Africa and the Middle East in terms of water scarcity. With good future planning, modeling will help to solve water scarcity problems in the Ismailia canal, which is one of the most significant branches of the Nile River. Many previous studies of the Nile river basin depended on quality modeling and hydro-economic models which had policy or system control constraints. To overcome this deficit position and number, the East Nile Delta area was investigated using LINDO (linear interactive, and discrete optimizer) software; a mathematical model with physical constraints (mass balances); and ArcGIS software for canals and water demands from the agriculture sector, which is expected to face a water shortage. Using the total capital (Ismailia canal, groundwater, and water reuse) and total demand for water from different industries, the software measures the shortage area and redistributes the water according to demand node preferences (irrigation, domestic, and industrial water demands). At the irrigation network’s end, a water deficit of 789.81 MCM/year was estimated at Al-Salhiya, Ismailia, El Qantara West, Fayed, and Port Said. The model was then run through three scenarios: (1) the Ismailia Canal Lining’s effect, (2) surface water’s impact, and (3) groundwater’s impact. Water scarcity was proportional to lining four sections at a length of 61.0 km, which is considered to be optimal—based on the simulation which predicts that the Ismailia canal head flow will rise by 15%, according to scenarios—and the most effective way to reduce water scarcity in the face of climate change and limited resources as a result of the increasing population and built-in industrial projects in Egypt
Headache attributed to ischemic stroke – a new scope for management: a case study
No full textAcute ischemic stroke may present with serious clinical manifestations. Headache attributed to ischemic stroke is one of these clinical manifestations which may be neglected and affect the functional outcome of the patients. Understanding the exact pathophysiology, and recognition of the most clinical and radiological predictors can help to provide good management and open scope for prophylactic approaches. Here, we report a case presented with acute onset of ischemic stroke and developed a new onset headache on the first day of stroke onset. According to the International Classification of Headache Disorders third edition (ICHD-3), the patient has a post-stroke headache. Using transcranial duplex ultrasound, activation of the trigeminovascular pathway could be attributed to the opening of more pain-sensitive collateral channels as the left posterior communicating artery (P Com A). In conclusion, we can predict the development of acute headache at stroke onset based on different clinical and radiological factors. Opening of the collateral channels is strongly implicated in the production of post-stroke headache
