This construction method offers numerous benefits, including damage resistance, good service response, and low cost. The advantages can be further enhanced through the use of X-HVB shear connectors instead of traditional weld-on bolts. X-HVB connectors offer two additional benefits: they can be used in cold rolled profiles, wet sections or rehabilitation elements, and their installation is simple and safe. The connectors are made of cold-rolled steel and come in a range of nominal heights from 40 to 140 mm. However, little previous research has focused on how the X-HVB connectors behave and affect composite beams during a fire. To investigate this, an experimental study was conducted that focused on the effect of fire exposure, the orientation ...

Moreover, the ability of these polymer entanglements to damp turbulence waves and changing the flow regime has been tested at various conditions, and a clear observation showed that the maximum drag reduction always occurs when the highly fluctuated waves were reduced effectively by DRP (and that, accordingly, phase transition (flow regime changed) appeared. This may also help in improving the separation process and enhancing the separator performance. The present experimental set-up has been constructed using a test section of 1.016-cm ID; an acrylic tube section was used to enable visual observations of the flow patterns. A new injection technique has been utilized and, with the use of different injection rates of DRP, the results have s...

In this paper, a fully automated model is designed using deep learning algorithm to capture images from patients and pre-process, segment and classify the intensity of cancer spread. In the first pre-processing step, pectoral muscles are removed from the input images, which are then downsized. The removal of pectoral muscles after identification may become crucial in classification systems. Finally, the pectoral musclesaredeleted from the picture by using an area expanding segmentation. All mammograms are downsized to reduce processing time. Each stage of the fully automated model uses an optimisation approach to obtain highaccuracy results at respective stages. Simulation is conducted to test the efficacy of the model against state-of-art models, and the ...

Since flow of knowledge usually happens in a particular context, context has to be taken into consideration in knowledge flow modeling. Past models of flow of knowledge lacked in terms of software development and lacked in-depth exploration of context modeling, which made those models less applicable. This research proposes a conceptual framework of context oriented flow of knowledge in software development aspects. In this framework, the context is seen as an inseparable element of flow of knowledge, which is regarding the creation, transformation as well as application of knowledge items. Framework KFFD is proposed based on three aspects-flow of knowledge, software development project and ontology. For the proper use of knowledge, dynamic flow to destinations form sources is necessary. In this context, a new framework in KM is analyzing, designing and implementing know...

There are different definitions for this term, ranging from any system that has sensors and actuators to a solitary interconnected network of physical items. This Paper shows that this term does not give enough information to construct a software architecture on. This is accomplished by taking an inside look at the IoT described in literature as well as the types of applications that exist on the market today and using the concept of software architectural styles to show how different areas in the IoT will need varying styles. This paper continued to classify solutions in the Internet of Things into different classes. The outcomes are that for a subset of the classes there is a reasonable style, however for remaining classes there are still different decisions where more context information is needed.

Based on the hybrid transformations, a new technique of sharing scheme with excellent sharing-control flexibility is suggested to share a secret image into multiple shadow pictures (for N users) utilizing a scheme of Shamir’s threshold beside a method for solving a system of linear equations by Gaussian Elimination to remade the secret. This scheme applied a hybrid I-WT and DCT firstly to de-correlate image pixels for more reduction in image size; then it employs the modifying Shamir’s (k, n) sharing scheme to generate the shadow images. A quality refinement of the recouped picture is accomplished by the information collected from the threshold (k) of share images, and each of one has no data about the secret image. The shadow image size for everyone is smaller than [1/3.5*(v / k- 0.1)] of the secret i...

One of the most challenging things about cancer treatment is not the cure itself but the differentiation between the tumor cells and the normal cells. Most of the medical treatments of the cancer today cannot differentiate between the cancer cells and the normal one as well as it damages the hall tissue and it is still considered as a low-effect treatment to be applied in cancer. One of the most popular treatments of this kind is chemotherapy which is known for damaging the hall cells, cancer, and normal ones. Our research is focusing on generating a new therapy that can target the cancer cell itself so it will give us more efficiency ratio to stop cancer and will keep the other cells without any damage. We will use an antibody body for the protein antigen ErbB-2 which is located rabidly in the lung cancer cells' membrane surface. These antibodies will be produced by the immune system so it will target the tumor cells especially and stop the cell growth and damage it in some cases.
