Disilver(I) palladium(II) diphosphate, Ag(2)PdP(2)O(7), is isotypic with Na(2)PdP(2)O(7). It consists of infinite diphosphato-pallad-ate(II) [Pd(P(2)O(7))(2/2)](2-) ribbons with the Pd(II) ion in an almost square-planar coordination ( symmetry) and the P(2)O(7) group exhibiting 2 symmetry. The [Pd(P(2)O(7))(2/2)](2-) ribbons are linked by distorted [AgO(6)] octa-hedra. (31)P-MAS NMR studies on ...

Approximate ripple carry adders (RCAs) and carry lookahead adders (CLAs) are presented which are compared with accurate RCAs and CLAs for performing a 32-bit addition. The accurate and approximate RCAs and CLAs are implemented using a 32/28nm CMOS process. Approximations ranging from 4to 20-bits are considered for the less significant adder bit positions. The simulation results show that approx...

Models are abstract representations of reality that are built, analyzed and manipulated to augment the understanding of that reality. They can either be mental or codified but, in both cases, they contribute to good decision-making by ensuring that the right people use the right information at the right time. In order to reduce time to market, companies commonly adopt product development proces...

Decisions about product development in mass customization (MC) are crucial but complex. It is suggested the use of Decision Support Systems (DSS) to improve decision-making within the product development process (PDP) in mass customization systems to better serve not only to organizational demands, as well as to market demands. Thus, we conducted an exploratory literature review aiming to ident...

The present paper describes the work done at SLAC for the magnetostrictive wire spark chambers of SPEAR, LASS and the two-meter streamer chamber. All three are CAMAC systems based on the use of a time digitizer module with different interfacing techniques into three different computers (Sigma 5, PDP-9, PDP-11). Of particular interest is a display controller module that permits wide selection of...

In this paper, we present a performance comparison of existing clocked dynamic comparators. As delay is directly correlated with the submicron scaling, we investigate the performance of the above comparators in terms of delay and Power-Delay Product (PDP). PDP gives the average energy dissipated by the comparator for a single comparison. Simulation results using Mentor Graphics revealed better ...

This paper illustrator* tho methodology of the CMU Design Automation System by presenting, an automated design of the PDP-8/E data palhs from a functional description. This automated clnsign (using synthesis techniques) is compared both to DECV, implementation and the Intersil single chip implementation.

The paper proposed a new design for implementing semi-static flip-flop for low power and high performance applications. In this work, comparative analysis of six existing flip-flop designs along with the proposed design is made. The proposed design has better power, delay and PDP than the existing architectures. All simulations are performed on TSpice using BSIM models in 130 nm process node. T...

PDP (Protocol Diaqnostic Program) is a proqram for analyzing think-aloud protocols of subjects solvinq elementary physics problems *. Two versions of PDP implement models of problem solving behaviour at novice and intermediate levels of expertise. In order to compare the behaviour of the models with think-aloud protocols of subjects, PDP is equiped with a think-aloud component, which communicat...
