Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 12-26

The sophisticated, cutting-edge low power, low cost wireless technologies of today make the Internet of Things (IOTs) a significant platform. IOT applications are being used on an increasing basis in a variety of contexts, including smart factories, smart cities, smart industries, and smart homes. Achieving a suitable level of precision and accuracy in localizing the person, object, or device is crucial for each of these applications. In IOT, every gadget is connected to every other device through the internet. One way to classify localization is as measurements of area, angle, distance, etc. Numerous wireless technologies, including radio frequency identification (RFID), Bluetooth low energy (BLE), WiFi, and ultra-wideband (UWB), are utilized in Internet of Things (IOT) systems to achieve dependable localization. It has been discovered that UWB plays a crucial function. Since UWB has a wide frequency range (3.1GHz–10.6GHz), a low duty cycle (maximum on time 5ms and off time 38ms), high accuracy of ranging (cm), uses very small pulses (ns to localize), can pass through obstacles, can prevent multipath fading, and other advantages, it has been found to be important for localization in IOTs. It performs well in a wireless sensor network (WSN) and has been looked into as a possible option for indoor localization. We present the age and gathering of UWB signal first and afterward we examine the confinement calculation for IoT applications utilizing UWB remote innovation.

Harena Chan-Se Maharisoa, Mohamed Tahiri

Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 27-44

We aim to develop low-cost technologies for the treatment and reuse of rural domestic wastewater in agricultural irrigation and landscaping. These technologies are based on gravity flow and do not require energy for pumping, agitation, or aeration. Additionally, the sludge generated from the mini-Steps can be used as organic fertilizers for agriculture. The chosen technologies are CAR or UASB reactor. The structures are designed based on the average daily flow rate and constructed using local concrete. The treated water storage basin is also covered to prevent accelerated evaporation caused by sunlight, particularly in sub-Saharan countries that are vulnerable to the impacts of climate disturbances.

Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 45-61

This chapter describes the performance of a Solar PV-powered switched reluctance motor with low torque ripple in electric vehicle applications. The conspicuous impression of solar energy in our nation’s energy requirements has become predominant in recent years. It is a boundless source of energy and the finest substitute for any other non-renewable sources in our country. Switched reluctance motors have become increasingly common in the electric car sector due to their unbreakable features, which include their self-starting ability, simple structure, lack of rotor windings, and low maintenance requirements. However, because to its nonlinear features, SRM's large torque ripple is a constraint. This paper analyzes the performance of a switching reluctance motor with several DC-DC converters, and compares the findings in terms of the motor's speed and torque ripple %. The switching time of the converter is controlled by the MPPT controller, which uses incremental conductance and the Integrator method. The converters presented in this work are the Boost converter and the Cuk converter. These two types of converters are designed in MATLAB software and their characteristics are analysed while supplying the switched reluctance motor. . The DC-DC converter output is given to the input of power converter, which is asymmetric bridge converter. This converter drives the switched reluctance motor under variable load conditions. By varying the duty cycle of the DC-DC converter circuit the output voltage can be controlled. This in turn controls the speed of the motor effectively. The findings of the simulation are used to analyze how well the suggested system works with the motor. From the results, it is evident that using this kind of converter improves the speed and torque ripple performance of the solar PV powered switched reluctance motor. Hence, it is suitable for electric vehicle applications, which require less torque ripple and mechanical vibrations.

An Effective Scheme for Revocation of User Attributes for Data Outsourcing in Cloud Storage

Fang Zheng, Xinguang Peng, Zhidan Li

Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 62-87

This chapter proposes a novel and fast scheme based on CP-ABE algorithm from the respect of the user’s attribute revocation to make it faster. With the advances of cloud data centers and cloud service, many application scenarios are developed such as enterprise business, the Vehicular Ad Hoc Networks (VANET), Sensor network. VANET is a particular case of wireless multihop network, which has the constraint of fast topology changes due to the high node mobility. Two major issues are efficiency and confidentiality. One of the fine-grained access control cryptography technologies, CP-ABE, is frequently used in cloud storage for outsourced data to safeguard user privacy. Furthermore, in addition to anonymity, computational cost is a key component that enables the use of CPABE in the circumstancesIn this scheme, we construct an identical tree T2 that has the same structure as the actual access control tree T1. Upon receiving a request from the user for the encrypted text to be preserved on CSP, CSP attempts to decrypt CT2, which is encrypted using the subset of secret keys that correspond to the user-provided attribute indexes and is also preserved on CSP based on the same tree T2. CSP will send CT1 to the user if they are able to decrypt it successfully, as this verifies their authorization to access the cryptographic text. In the event that CT1 is not sent to the user, CSP acknowledges that the user does not have access to it. Namely, we can decide if we authorize the right to access CT1 by judging if the secret key provided by the user can decrypt CT2. Because CT1 and CT2 have the same access control structure, they have the same secret key for decryption; that is, when some attributes are revoked, if the secret key cannot decrypt CT2, it cannot decrypt CT1. While CSP can directly decrypt CT2, but not CT1, CSP can judge if the  user has access to CT1 after the attribute revocation by decryption of CT2. Moreover, we propose the construction method of CT1 and CT2. Finally, we prove that the scheme is secure and viable. Our scheme realizes the attribute revocation and does not add too much computation overload on the system.

Working with Nature to Manage Tidal Inlets

Jonathan Akin French

Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 103-119

Sandy inlets are in a dynamic equilibrium between wave-driven littoral drift acting to close them, and tidal flows keeping them open. Their beds are in a continual state of suspension and deposition, so their bathymetry and even location are always in flux. Even so, for sandy inlets a nearly linear relationship between an inlet’s cross-sectional flow area and the inshore tidal prism is maintained - except when major wind and/or runoff events act to close or widen an inlet. Inlet location can be stabilized by jetties, but dredging may still be necessary to maintain a navigable channel. Armoring with rock large enough to resist erosion can protect an inlet bed or river mouth from excessive storm flow erosion. Armoring can also be used as a strategem to close inlets.

MAC Address Cloning Technique Results

Md. Abdullah Yusuf Imam , Prodip Kumar Biswas

Contemporary Perspective on Science, Technology and Research Vol. 2, 29 December 2023, Page 120-129

MAC address cloning causes the Docker container to use the MAC address of the host, and the host to use the MAC address of either an address you specify or a randomly generated one. MAC filtering is not an effective way in wireless networking as attackers cannot search easily MAC address on wireless transmissions mode. On the other hand, in a wired network, MAC filtering works better since it is simpler for an attacker to determine an approved MAC address. Every LAN card has a unique MAC address allocated to it. In this way, Changing MAC address is necessary in network virtualization. It can also be used in the process of exploiting security of a system. By cloning MAC address makes one device hidden from outsider, in the same way cloning MAC address makes a network vulnerable. It is important to choice who wants to do what. In IP networks, the MAC address of an interface is query given the IP address using the Address Resolution Protocol (ARP) for Internet Protocol Version 4 (IPv4) or the Neighbor Discovery Protocol (NDP) for IPv6. ARP and NDP are used to relate IP addresses (OSI layer 3) to Ethernet MAC addresses (OSI layer 2). Security can be enhanced through MAC address cloning because it enables you to use a dedicated virtual NIC for the Admin Network, Grid Network, and Client Network. Having the Docker container use the MAC address of the dedicated NIC on the host allows you to avoid using promiscuous mode network configurations.

At present, the e-Toilet system which exists are operates manually. Seeing, current situation of Covid-19 and Omicron there is a risk to use such manual system. So, by considering health and hygiene factor we are trying to give a solution which can solve issues related to cleanliness by using a automated system. e-Toilets are self-contained, self-cleaning, user-friendly, unmanned, automated toilet pots installed in public places. The entire unit is made of stainless steel. E-Toilets have sensors to initiate automatic functions.

E-Toilet is a coin operated pay Toilet. Multiple sensors are used to automate the whole system. The whole sensor data is provided to authorize person through IoT. The waste water from the system is then supplied to the underground tank through which it goes for purification purpose. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment.

Wastewater Plant is used here, that will treat the outlet water coming out from e-Toilet system and make the reusable water which will further used for multiple purposes like for Agriculture purpose. So in this way we can control a lot of diseases that are occurring because of wastewater.
