In recent years, Software-as-a-Service (SaaS) is gaining momentum with more and more successful adoptions. Several companies including some well known names have embraced this new model for software distribution. In this paper we present ODBIS, an open source infrastructure to build and deliver On-Demand Business Intelligence Services. The ODBIS platform(More)
The new current design is especially suitable for use in mu lti-standard wireless receiver fo r microwaves communicat ion systems. In recent years, there has been a growing market for dual band transceivers for various wireless standards. This work investigates a novel circuit topology of concurrent Dual-band Low No ise Amplifier (LNA) operates in the 3.9(More)
In recent years, the data warehousing infrastructures have undergone many changes in various aspects. This is usually due to many factors: the emergence of Software-as-a-Service (SaaS) architecture model; the success of agile and iterative Data Warehouse (DW) development approaches; the introduction of new approaches based on the Model Driven Architecture(More)
This paper studies a new machine learning application with possibly a challenging benchmark for relational learning systems. We are interesting in the automation of Model-Driven Data Warehouse [6, 13, 2] using machine learning techniques. Intend is to automatically derive the transformations rules to be applied in the model-driven process. This aims to(More)
Model transformation in the context of Model-Driven Data Warehouse is ensured by human experts. It generates an exorbitant cost and requires high proficiency. We propose in this paper a machine learning approach to reduce the expert contribution in the transformation process. We propose to express the model transformation problem as an Inductive Logic(More)
In first stage of each microwave receiver there is Low Noise Amplifier (LNA) circuit, and this stage has important rule in quality factor of the receiver. The design of a LNA in Radio Frequency (RF) circuit requires the trade-off many importance characteristics such as gain, Noise Figure (NF), stability, power consumption and complexity. This situation(More)
