    In this article, the chemical kinetics problem is presented. The Differential Transformation Method (DTM) is presented to find an approximate analytical solution to the chemical kinetics problems. Proposed problem is system of nonlinear ordinary differential equations. We show converges analysis of the differential transform method. DTM applied to two examples. The method shows the form of fast converging series and the results prove the applicability of the proposed method, which gives accurate results.

    Wireless Sensor Networks (WSNs) have many potential applications and unique challenges. They usually consist of hundreds or thousands small sensor nodes such as MICA2 which operate autonomously conditions such as cost invisible deployment and many application domains, lead to small size and limited resources sensors. WSNs are susceptible to many types of link layer attacks and most of traditional networks security techniques are unusable on WSNs  due to wireless and shared nature of communication channel, untrusted transmissions, deployment in open environments, unattended nature and limited resources. So, security is a vital requirement for these networks; but we have to design a proper security mechanism that attends to WSN's constraints and requirements. In this paper, we focus on security of WSNs, divide it (the WSNs security) into four categories and will consider them, include: an overview of WSNs, security in WSNs, the threat model on WSNs, a wide variety of WSNs' link layer attacks and a comparison of them. This work enables us to identify the purpose and capabilities of the attackers; also, the goal and effects of the link layer attacks on WSNs are introduced. Also, this paper discusses known approaches of security detection and defensive mechanisms against the link layer attacks; this would enable it security managers to manage the link layer attacks of WSNs more effectively.

    Remote correspondence advancements are making new sensor capacities. The current advancements in the field of sensor networks are basic for ecological applications. Web of Internet of Things (IoT) permits associations among different gadgets with the capacity to trade and accumulate information. IoT additionally stretches out its ability to ecological issues notwithstanding computerization industry by utilizing industry 4.0. As water is one of the fundamental necessities of human endurance, it is expected to consolidate some instrument to screen water quality opportunity to time. Around 40% of passing’s are caused because of defiled water on the planet. Subsequently, there is a need to guarantee supply of filtered drinking water for individuals both in urban areas and towns. Water Quality Monitoring (WQM) is a practical and proficient framework intended to screen drinking water quality which utilizes IoT innovation. In this paper, the proposed framework comprises of a few sensors to gauge different boundaries, for example, pH esteem, the turbidity in the water, level of water in the tank, temperature and mugginess of the encompassing air. And furthermore, the Microcontroller Unit (MCU) connected with these sensors and further handling is performed at Personal Computer (PC). The got information is shipped off the cloud by utilizing IoT based Think Speak application to screen the nature of the water.

    Agriculture is the primitive and crucial occupation for the people. Smart Agriculture (SA) is an emerging concept, because IOT sensors are capable of providing information about agriculture fields and then act upon based on the user input. Urbanization, which indirectly affected the lives of people in the agricultural sector by increasing level of environmental pollution, climate change, degradation of soil and water quality, increasing population, decreasing income from the farming industry, etc. In this Paper, it is proposed to develop a SA System that uses advantages of cutting-edge technologies such as Arduino, IOT and Wireless Sensor Network (WSN). Internet of Things (IoT)-based smart sensors is the new technique for the SA system. IoT-based SA system consists of various sensor nodes placed in different locations, internet service, smart remote devices, or computer systems with the internet that monitor the operation of sensor nodes, Wi-Fi, a camera with a microcontroller, and different interfacing sensing nodes for service. The system has a duplex communication link based on a cellular-Internet interface that allows for data inspection and irrigation scheduling to be programmed through an android application.

    Humanity is currently experiencing one of the short periods of transition thanks to novel sensing solutions for smart cities that bring the future to today. Overpopulation of cities demands the development of solid strategic planning that uses infrastructure, innovation, and technology to adapt to rapid changes. To improve mobility in cities with a larger and larger vehicle fleet, a novel sensing solution that is the cornerstone of a smart parking system, the smart vehicular presence sensor (SPIN-V, in its Spanish abbreviation), is presented. The SPIN-V is composed of a small single-board computer, distance sensor, camera, LED indicator, buzzer, and battery and devoted to obtain the status of a parking space. This smart mobility project involves three main elements, namely the SPIN-V, a mobile application, and a monitoring center, working together to monitor, control, process, and display the parking space information in real-time to the drivers. In addition, the design and implementation of the three elements of the complete architecture are presented.
