Design and Analysis of Bi-planar Antenna for Long Term Evolution Base Stations
Full text linkIn this article, A bi-planar receiving antenna is planned for LTE convenient base stations. The proposed reception apparatus involves two parts one for the upper band and another for lower band. It can in like manner be shown without granulating folds. The lower band has the pair of printed dipoles with two or three parasitic parts for transmission limit improvement. The upper band contains a few crumbled dipoles. The microstrip line and dipole are cut on a comparative substrate. The upper band segments are wrapped in lower band segments encircling a diminished structure. The bi-planar receiving wire achieves an information transmission of around 2 GHz. The arranged receiving wire can be completed in versatile base stations. The radio wire increase achieved around ~12 dbi which is sensible for the adaptable correspondence base station structures
The b-Coloring of graphs in Bistar and Its Various Properties
Full text linkA graph's b-coloring iswhenG its vertices are properly colored so that every color class has a vertex connected to at least one vertex in every other color class. In graph Gthe b – chromatic number denoted by ????(G),is the maximal integer k such that G may have a b – coloring with k- colors. In the present study, we derive the b-chromatic number for the corona product of the Bistar graph, which is represented by the following:????(Bn,n ° Pn), ???? (Bn,n ° Cn), ???? (Pn ° Bn,n), ????(Cn° Bn,n)respectively
The Gig and Sharing Economy: Transformations, Challenges, and Organisational Responses
No full textThe rise of the gig and sharing economy in the 2010s represents one of the most significant shifts in labour markets and business models since the advent of industrial capitalism. Enabled by digital platforms such as Uber, Airbnb, TaskRabbit, and Upwork, this new economy reshapes the relationship between firms, workers, and consumers. It challenges traditional understandings of employment, regulation, and value creation. This article explores the drivers of the gig and sharing economy, including technological innovation, consumer preferences, and globalisation. It then examines key challenges: worker precarity, regulatory ambiguity, market concentration, and ethical dilemmas. Strategic responses are identified for firms, policymakers, and workers, including platform governance, social protection mechanisms, and collaborative models. Sectoral case studies in transport, hospitality, freelancing, and retail provide practical insights into successes and failures. Broader implications for labour rights, taxation, and the future of work are also analysed. The central argument is that the gig and sharing economy cannot be dismissed as a passing trend; it is an enduring transformation that requires innovative governance and inclusive strategies to ensure fairness, sustainability, and legitimacy
Hybrid Hand-off Scheme for Performance Improvisation of Wireless Networks
Full text linkWireless systems administration is turning into an inexorably significant and well known method of giving worldwide data access to clients progressing. Handoff, the procedure where portable hubs select best passageway accessible to move information and its postpones make a major issue. A great deal of research has been done in most recent years to diminish the handoff delays happen in the various degrees of WLAN correspondence. Because of the versatility of handoff, significant viewpoint in WLAN and cell correspondences are substantially more significant. Because of constrained scope of APs, WLAN likewise gives adequate data transmission to continuous spilling administrations. In this research article, various handoff plans are proposed to diminish the hand-off idleness and bolster quick hand-off in IEEE 802.11arcchitecture of wireless networks. In this article, we survey these quick handoff plots subjectively. In this work it is to make accessible preparation for prospect research on lessening the handoff inertness and give accentuation on necessity of quick handover for consistent network
Monitoring of Drainage System in Urban Using Device Free Localization Neural Networks and Cloud computing
Full text linkWireless Sensor Network is a Wi-Fi community consisting of spatially propagated and self-sufficient devices using sensors to detect physical or environmental conditions. During heavy rainfall, the urban drainage system cannot drain the water. A wireless sensor with many interconnected wireless sensor nodes captures real-time data from the network environment and transmits this data to a base station for analysis and operation. With wireless sensor nodes, it is possible to capture and monitor the amount of water in drainages and the difference in water flow between the two points in the drainage system. Nevertheless, the majority localization techniques aims on device based localization, which can find target with festinated devices. It is not suitable for applications such as terrain, drainage flow and flooding. Here device free wireless localization system using artificial neural networks and a cluster based wireless sensor network system to monitor urban drainage is proposed. There are two stages in the system. During the off-line preparation stage, Acceptable Signal Strength (RSS) differential metrics are calculated between the RSS metrics together while the monitor area is empty and calculated by a specialized in the region. Some RSS dissimilarity values ??are selected in the RSS Difference Matrix. The RSS dissimilarity standards ??and associated matrix indices are taken as the inputs of the ANN representation in addition to the identified position coordinate are in its outputs. The real-time data collected from the wireless sensor network is used to detect overflow and provide alarms before disturbances arise
Analysis and Implementation of Hybrid FIR Architecture in Speech Processor
Full text linkHearing aid is an electronic gadget precisely used into the internal ear which reestablishes halfway hearing to smooth hearing. The discourse processor of CI parts the sound-related sign into groups of various frequencies and changes over them into appropriate codes for animating the cathodes in cochlea of ear. The cathode actuates sound-related nerve filaments to give hearing sensation. The expense of the CI alone goes to around 100,000 US dollars. For the efficient less well-to-do individuals with hearing sickness, it might be too exorbitant to even consider affording for this hardware to recoup from the conference misfortune. It gets important to cut down the expense. The cost decrease might be accomplished with diminished region, low force and rapid activity of the CI. This goal intuited both the simple and the computerized based CI originators to inquire about their techniques to give individuals less expensive and profoundly understandable CI. The primary objective of this paper is to develop reconfigurable DSP architectures for the filter banks in speech processor of CI with the following features like minimized area of the filter, reduced power consumption of the speech processor and enhanced presentation of the filter. This paper involves the design and hardware implementation of narrow band pass FIR filter for speech processor of CI using the Xilinx System Generator (XSG) tool on Virtex 7 FPGA
