The Hilbert functions and the regularity of the graded components of local cohomology of a bigraded algebra are considered. Explicit bounds for these invariants are obtained for bigraded hypersurface rings. Introduction In this paper we study algebraic properties of the graded components of local cohomology of a bigradedK-algebra. Let P0 be a Noetherian ring, P = P0[y1, . . . , yn] be the polyn...

This work describes the implementation of health monitoring system using Lilypad Arduino microcontroller and ESP8266 Wi-Fi module. The system is developed to monitor the real-time heart rate and body temperature of a patient remotely. The components used in this work are pulse sensor to pick up the rate of heart beat signal and Lilypad temperature sensor to detect body temperature from the pati...

In recent years, the ZigBee network has been rapid develop in smart home. In order to solve the interconnection problem between the ZigBee network and the internet in the smart home, a wireless home gateway based on embedded is designed and implemented in this paper. The gateway is made up of the main controller S3C2440, the ZigBee module JN5148 and the Wi-Fi module VT6656. It is capable of con...

In rapidly developing technology, most of engineering applications need to be done remotely. An antenna is needed transmit the values ​​received as a result these remote studies. The type that more suitable use in line with this Wi-Fi antenna. Although low cost, it provides benefits user by using good band. study, design at 2.4 GHz frequency for E-Health kit-based biotelemetry module discussed....

Th e American pension environment is undergoing a dramatic shift from defi ned benefi t, in which the amount of retirement benefi ts are determined largely by years of service, to defi ned contribution, in which retirement wealth depends on how much workers save and how they allocate their pension wealth. A wide range of fi nancial products are now available for retirement saving, and workers a...

Smartphones and tablets including phone, calendar and others are the necessities of modern man. They are one of the MN (Mobile Nodes), each with wireless network capabilities. Necessities of modern human MNs are almost included in every cellular module available in LTE/3G and Wi-Fi module for high-speed Internet. Until now, MN mobility management is handled in a traditonal way, but network-base...

a presentation of M , where F is a free module of arbitrary rank. Let U denote the matrix (with n rows but possibly infinitely many columns) representing φ with respect to some fixed bases for F and An. For t ≥ 1 we let It(φ) denote the ideal of A generated by all t-sized minors U . (This ideal is independent of the choice of bases.) By convention, It(φ) = R for t ≤ 0 and It(φ) = 0 if t exceeds...

We study the coinduction functor on the category of FI-modules and its variants. Using the coinduction functor, we give new and simpler proofs of (generalizations of) various results on homological properties of FI-modules. We also prove that any finitely generated projective VI-module over a field of characteristic 0 is injective.

With the wide deployment of Wi-Fi networks, Wi-Fi based indoor localization systems that are deployed without any special hardware have caught significant attention and have become a currently practical technology. At the same time, the Magnetic, Angular Rate, and Gravity (MARG) sensors installed in commercial mobile devices can achieve highly-accurate localization in short time. Based on this,...
