TL;DR: In this paper, the notion of compatibility of mappings in a partially ordered metric space was introduced and used to establish a coupled coincidence point result, which was later extended to fixed point theorems.
Abstract: In this paper we introduce the notion of compatibility of mappings in a partially ordered metric space and use this notion to establish a coupled coincidence point result. Our work extends the work of Bhaskar and Lakshmikantham [T. Gnana Bhaskar, V. Lakshmikantham, Fixed point theorems in partially ordered metric spaces and applications, Nonlinear Anal. TMA 65 (2006) 1379–1393]. An example is also given.

TL;DR: A simple prey-predator model under impreciseness is considered and parametric functional form of an interval is introduced and the solution in the interior equilibrium is obtained using Pontryagin's maximum principle.
Abstract: The paper presents the study of one prey one predator harvesting model with imprecise biological parameters. Due to the lack of precise numerical information of the biological parameters such as prey population growth rate, predator population decay rate and predation coefficients, we consider the model with imprecise data as form of an interval in nature. Many authors have studied prey–predator harvesting model in different form, here we consider a simple prey–predator model under impreciseness and introduce parametric functional form of an interval and then study the model. We identify the equilibrium points of the model and discuss their stabilities. The existence of bionomic equilibrium of the model is discussed. We study the optimal harvest policy and obtain the solution in the interior equilibrium using Pontryagin’s maximum principle. Numerical examples are presented to support the proposed model.

TL;DR: The novel way of carrying out an integrated sensing system which automates the solid waste management process is presented, based on ultrasonic-level sensor and various gas sensors which automatically sense the hazardous gases and the maximum limit of waste.
Abstract: Clever solid waste bin is important to create a well-organized and dynamic waste management system. This paper presents the novel way of carrying out an integrated sensing system which automates the solid waste management process. The proposed smart waste bin is based on ultrasonic-level sensor and various gas sensors which automatically sense the hazardous gases and the maximum limit of waste. The approach is unique and uses cloud and mobile app-based monitoring. Two important features of work are it not only checks the maximum waste level of the bin but also checks various stinky gases. The other part of the work is conveying the information to the responsible authority. This unique approach takes the assistance of cloud sever because of its advantages in field of usability, accessibility and disaster recovery. The information can be linked with municipality web server for immediate action. The waste bins are tracked by a unique number which represents its location. The eccentric technique gives all information related to physical condition of a particular bin and can easily reach the corresponding authority. The whole information is interconnected with a cloud-based web-information system at the host server.

TL;DR: In this paper, a simple rectangular microstrip antenna on slot-type defected ground plane is proposed for reduced cross-polarized (XP) radiation and justified theoretically, which will reduce the XP radiation field compared to a conventional micro-strip antenna without affecting its copolarised (CP) radiation characteristics.

TL;DR: In this paper, a rectangular microstrip patch on a composite substrate is theoretically and experimentally investigated, and the proposed configuration shows as much as 75% increment in beam width in its H-plane and nearly 10% in E-plane, indicating peak gain of the order of 8 dBi.
Abstract: A rectangular microstrip patch on a composite substrate is theoretically and experimentally investigated. Considerably wide radiation beamwidth along with high gain is experimentally demonstrated. Compared to a conventional microstrip patch, the proposed configuration shows as much as 75% increment in beam width in its H-plane and nearly 10% in E-plane, indicating the peak gain of the order of 8 dBi.
