1 This work was sponsored in part by ARPA under grant DAAH04-94-G-0004 Abstract This paper discusses the design and development of a general-purpose programmable DSP subsystem packaged in a multichip module. The subsystem contains a 32-bit floating-point programmable DSP processor along with 256 K-byte of SRAM, 128 K-byte of FLASH memory, 10 K-gate FPGA and a 6-channel 12-bit ADC. The complete ...

We generalize the Serre-Swan theorem to non-commutative C∗algebras. For a Hilbert C∗-module X over a C∗-algebra A, we introduce a hermitian vector bundle EX associated to X . We show that there is a linear subspace ΓX of the space of all holomorphic sections of EX and a flat connection D on EX with the following properties: (i) ΓX is a Hilbert A-module with the action of A defined by D, (ii) th...

Let $A$ be a Banach algebra and $E$ be a Banach $A$-bimodule then $S = A oplus E$, the $l^1$-direct sum of $A$ and $E$ becomes a module extension Banach algebra when equipped with the algebras product $(a,x).(a^prime,x^prime)= (aa^prime, a.x^prime+ x.a^prime)$. In this paper, we investigate $triangle$-amenability for these Banach algebras and we show that for discrete inverse semigroup $S$ with...

Concentrat ion polarisation, decreasing the efficiency in membrane separation processes, can be reduced by increasing mass t ransfer between membrane surface and bulk of the feed stream. Analogous to techniques used in plate heat exchangers efforts have been made to enhance mass t ransfer in a plate hyperfiltration module by using a corrugated membrane in stead of a flat one. The corrugations a...

Large circuits, whether they are arithmetic, digital signal processing, switching, or processors, typically contain a greater portion of highly regular datapath logic. Datapath synthesis algorithms preserve these regular structures, so they can be exploited by packing, placement, and routing tools for speed or density. Typical datapath synthesis algorithms , however, sacrifice area to gain regu...

Experimental investigations were carried out on removal of arsenic from contaminated groundwater by employing a new flat-sheet cross flow membrane module fitted with a hydrophobic polyvinylidenefluoride (PVDF) microfiltration membrane. The new design of the solar-driven membrane module in direct contact membrane distillation (DCMD) configuration successfully produced almost 100 per cent arsenic...

the concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. the notion of free fuzzy modules was introducedby muganda as an extension of free modules in the fuzzy context. zahedi and ameriintroduced the concept of projective and injective l-modules. in this paper we give analternate definition for projective l-modules. we prove that e...

Rule-based languages are being used for ever more ambitious applications. As program size grows however, so does the overhead of team-based development, reusing components, and just keeping a large flat collection of rules from interfering. In this paper, we propose a module system for a small logicallymotivated rule-based language. The resulting modules are nothing more than rewrite rules of a...

We are developing a Time-of-Flight Positron Emission Tomography detector using flat panel micro-channel plate photomultiplier tubes (MCP PMT). The high-speed waveform sampling data acquisition is adopted to exploit the fast time response of MCP PMT efficiently by using transmission-line readout scheme. To demonstrate the feasibility of the proposed detector, prototype detector modules were buil...

where Hom(π1(X), G) denotes the space of all group homomorphisms from the fundamental group π1(X) into G, and G acts on this space by conjugation. Let φ : π1(X) → G be a homomorphism, and let [φ] denote the corresponding point of LocG(X). Note that φ defines a π1(X)-module structure on g via the adjoint representation of G. Let us denote this π1(X)-module by gφ, and let Eφ denote the associated...
