Android and Bluetooth Technology Enabled Remote Control Using Smart Phone
No full textABSTRACT:This paper proposes a universal remote control using Smart phone. User can control appliances easily by his Smartphone via Bluetooth. Around 71% of mobile developers use Android platform attributable to the recognition and extra features of the system. Phones are called smartphones only when applications like GPS, Video calling are embedded into the device. This paper combines Android, Bluetooth and smartphones which are three powerful technologies. Today's world without a Smartphone is very complex. As a result, we have combined the Remote control with the Smart phones and provide simple user interface, rather than complex number of buttons which we have seen in many universal remote controls. KEYWORDS:Universal Remote, PIC Micro controller, Bluetooth, Android, Smart Phones, Network. I.INTRODUCTION Nowadays, the number of appliance services and their complexity has increased. There is a need to get familiar with the different operations of many remote control manufacturers, which is very confusing. To overcome this problem they have built these remote controller, which is called Universal. Sometimes, such universal remote control has numerous buttons which is not user friendly. There are some researchers who have proposed a remote control for televisions.For the user interface, inconvenient by user need to click the button. They propose universal remote control device for Television and its connected entities. This paper is aimed at designing a device which can control the home appliances through smart phones. An android application is developed in the smart phone which enables us to control device through Bluetooth. A circuit has been designed where the microcontroller is connected to the relay and the Bluetooth device. Once the user switches on/off the appliance through the application developed in the smart phone, the command is received by the Bluetooth which is connected to the pin 26 (receiver pin) of the microcontroller. The microcontroller receives the command and enables the relay which is connected to the appliance to turn it on/off. In existing system, the devices will be controlled by manual operation. A person should go near to the appliance to switch ON/OFF the device. Although many wireless protocols exist they fail to provide compactness and user friendly interfaces to the user.The command is received by the microcontroller and it sends the value to the relay. The relay is connected to port C0 to C3 of the microcontroller. The relay acts as a switch and only pin of the relay is connected to the 230v supply and another is connected to the appliance. Thus depending upon the command sent the appliance is switched on .We have used 16F877A microcontroller. This controller is wide used for experimental and trendy applications owing to its low value, wide selection of applications, prime quality, and easy availableness. It is ideal for applications such as machine control applications, measuring devices, study purpose, and so on. The PIC 16F877 options all the elements that trendy microcontrollers commonly hav
Socially optimal allocation of ATM resources via truthful market-based mechanisms
No full textAbstract This is a position paper, complementing existing research on design of economic incentives for allocation of ATM resources and services. We show how to design mechanisms that can be used for the allocation of many different types of ATM resources, including tactical flow management slots and airport facility resources. In particular, we discuss the example of arrival management when multiple aircraft request the same landing time. The mechanisms we present are socially optimal (i.e., resources are distributed in the way that best serves the users community as a whole), truthful (i.e., each individual user has incentive to play fairly), and, under certain assumptions, individually rational (i.e., users lose nothing from entering the market). However, they are not budget balanced (i.e., the resource owner gains profit from the users' payments). Earlier, it was shown how to design individually rational, budget balanced and (sometimes) socially optimal mechanisms. We also discuss other possible desirable properties of resource allocation schemes, outlining directions for future research in the design of markets for ATM services
PHASE DISTORTION IN OPERATIONAL AMPLIFIERS
No full textABSTRACT The stray capacities in the input and feedback paths of an operational amplifier, its finite bandwidth and d.c. gain effectively narrow the bandwidth of an amplifier causing amplitude and phase errors in the computer solutions. A given degree of accuracy consequently becomes more difficult to obtain with an amplifier when used in a highspeed repetitive computer than when used in a slower machine. In a high-speed computer, phase distortion is more serious than the amplitude distortion. An attempt has been made in this paper to aoalyze an operational amplifier with its associated input-feedback networks and a practical method has been suggested for reducing the undesired phase shift. Introdttction. Macnee [1] has shown how the presence of undesired time constants associated with operational amplifier networks effectively narrow the bandwidth of an operational amplifier and consequently introduce amplitude and phase errors in the computer solutions of the differential equations. The errors get larger, and hence a given degree of accuracy becomes more difficult to obtain with an amplifier when used in a high-speed repetitive computer than when used in a slower machine. Bell and Rideout [2] in their analysis of an operational amplifier have assumed an amplifier with a finite bandwidth and the effect of finite bandwidth has been represented by a single equivalent time constant. The authors, however, have neglected the presence of stray capacities that are invariably associated with input and feedback networks of the amplifier. The authors have pointed out and emphasised the need for guarding against phase errors which are more serious than amplitude errors in the repetitive type of computers. An attempt has been made in this paper to analyse a physically realizable operational amplifier along with its input and feedback networks. The effect of finite bandwidth of an amplifier is assumed to be represented by a single equivalent time constant and the stray capacities in the input and feedback networks are taken into account
Brain Natriuretic Peptide Production and Secretion in Inflammation
No full textGene expression and secretion of the cardiac polypeptide hormones atrial natriuretic factor (ANF) and brain natriuretic peptide (BNP) are simultaneously upregulated in various cardiac disorders such as congestive heart failure, ischemic heart disease, and hypertensive heart disease, in which hemodynamic or neuroendocrine changes are key components in the progression of disease. However, during acute cardiac allograft rejection, plasma BNP levels are increased but not those of ANF. Successful treatment of the rejection episode decreases the elevated plasma BNP to prerejection values suggesting that substances related to inflammation may selectively influence BNP gene expression. Indeed, cytokines such as TNFα and IL-1β selectively stimulate cardiac BNP at the transcriptional and translational levels in cardiomyocyte cultures without affecting ANF. This selective BNP increase is seen in vivo, in addition to acute cardiac allograft rejection, in several circumstances where inflammation significantly contributes to the pathogenesis of disease such as in sepsis and in acute myocarditis

Resistance to and Accumulation of Heavy Metals by Actinobacteria Isolated from Abandoned Mining Areas
Get PDFAccumulation of high concentrations of heavy metals in environments can cause many human health risks and serious ecological problems. Nowadays, bioremediation using microorganisms is receiving much attention due to their good performance. The aim of this work is to investigate heavy metals resistance and bioaccumulation potential of actinobacteria strains isolated from some abandoned mining areas. Analysis of mining residues revealed that high concentration of zinc "Zn" was recorded in Sidi Bouatman, Arbar, and Bir Nhass mining residues. The highest concentration of lead "Pb" was found in Sidi Bouatman. Copper "Cu, " cadmium "Cd, " and chromium "Cr" were found with moderate and low concentrations. The resistance of 59 isolated actinobacteria to the five heavy metals was also determined. Using molecular identification 16S rRNA, these 27 isolates were found to belong to Streptomyces and Amycolatopsis genera. The results showed different levels of heavy metal resistance; the minimum inhibitory concentration (MIC) recorded was 0.55 for Pb, 0.15 for Cr, and 0.10 mg⋅mL −1 for both Zn and Cu. Chemical precipitation assay of heavy metals using hydrogen sulfide technic (H2S) revealed that only 27 isolates have a strong ability to accumulate Pb (up to 600 mg of Pb per g of biomass for Streptomyces sp. BN3)
MLCT excited states and charge delocalization in some rutheniumÁ/ ammineÁ/ polypyridyl complexes
No full textAbstract The ab initio calculations of polypyridine p*-orbital energies are the basis for assignment of the lowest energy, highest intensity metal-to-ligand charge transfer (MLCT) transitions in simple ammine Á/polypyridine Á/ruthenium(II) complexes. A gaussian analysis of the absorption and emission spectra of these complexes enables the evaluation of reorganizational energies for the vertical MLCT transitions from component bandwidths and from apparent vibronic progressions. The observed bandwidths are about half of the widths expected in the limit of no metal Á/ligand mixing. The excited state-ground state mixing coefficient, a DA , is inferred to be about 0.3 in [Ru(NH 3 ) 4 bpy] 2' based on this observation and a perturbation theory argument. These estimated reorganizational energies are combined with the observed ambient Stokes shifts to determine that the excited state electron exchange energy, K e , is small (600 Á/1200 cm (1 for 2,2? bipyridine complexes; Â/1500 cm (1 for 2,3-bis-(2-pyridyl)pyrazine complexes), but significant. This and the observation that the NÃ/H stretching frequency increases as the vertical MLCT energy (or a DA 2 ) decreases suggests that there is significant charge delocalization in these complexes. # 2002 Published by Elsevier Science B.V
Gross margins for NSW beef enterprises from 1999-2010
No full textAbstract: Erratic rainfall and rapidly changing world markets have led to volatile stock prices and variable returns to beef producers in recent years. Many producers have subsequently reviewed their choice of enterprise or management system and so an examination of long-term markets is useful when contemplating or advising on possible changes. A comparison of selected beef enterprise gross margins from 1999-2010 indicates that producers supplying markets with tighter supply specifications were generally rewarded with higher returns. For example, EU producers are obliged to maintain rigorous records, subjected to audits, and need improved pastures in order to produce heavy, finished, young cattle. Accordingly, returns in that enterprise have often been among the highest. Conversely, returns from weaner production were, on average, the lowest of those presented. There are no specifications for weaners; they can be produced from all classes of land and many producers revert to this production system during droughts or to realise quick returns. Note that rising input costs and variable market premiums have recently impacted most enterprises
