The Fifth Edition brings this widely recognized source to modern standards by ensuring that all information is relevant and contemporary. The material focuses on industry trends and successfully bridges the gap between the much higher levels of abstraction people in the field must work with today than in the past.
Abstract—A sequence of professional courses of study in Computer Engineering at the authors’ university was initiated. These included Digital Fundamentals, Programmable LogicDesign, Computer Hardware and Digital Systems Design. This paper presents a study on how the problem based learning has been used for these courses. It also describes how CDIO (Conceive, Design, Implement, Operate) concepts have been applied with an overview of all the hardware resources necessary to support the degree.
A virus is software that infects a computer by inserting itself into programs that already reside in the machine. Then, when the “host” program is executed, the virus is also executed. When executed, many viruses do little more than try to transfer themselves to other programs within the computer. Some viruses, however, per- form devastating actions such as degrading portions of the operating system, eras- ing large blocks of mass storage, or otherwise corrupting data and other programs. A worm is an autonomous program that transfers itself through a network, taking up residence in computers and forwarding copies of itself to other comput- ers. As in the case of a virus, a worm can be designed merely to replicate itself or to perform more extreme vandalism. A characteristic consequence of a worm is an explosion of the worm’s replicated copies that degrades the performance of legitimate applications and can ultimately overload an entire network or internet. A Trojan horse is a program that enters a computer system disguised as a desirable program, such as a game or useful utility package, that is willingly imported by the victim. Once in the computer, however, the Trojan horse per- forms additional activities that might have harmful effects. Sometimes these additional activities start immediately. In other instances, the Trojan horse might lie dormant until triggered by a specific event such as the occurrence of a preselected date. Trojan horses often arrive in the form of attachments to entic- ing email messages. When the attachment is opened (that is, when the recipient asks to view the attachment), the misdeeds of the Trojan horse are activated. Thus, email attachments from unknown sources should never be opened.

3.15 Cybervandalism: Vandalism that takes place using computer technology. The most common attacks are website defacement, malware to delete data, DDoS and social media account hijacking. 3.16 Cyberwarfare: Attacks in cyberspace that are aligned with a specific military operation or a national cybersecurity strategy to attack another nation‘s cyberspace. These operations have a military connotation that are led by commanders and executed by government cyber warriors. 3.17 Data breach: Disclosure of data or information that breaks confidentiality that leads to the distribution in the public domain. The leakage can occur by insider agents or hacker attacks. Damages can affect or trigger corporate reputation, financial losses, lawsuits, share prices, fraud and physical assets.
Compiled programming assignments contain executable computer applications, a standard and desired outcome. However, most email filters block these files due to the risk of viruses, so I must provide an alternate way for students to request help asynchronously. I’ve chosen a Moodle forum dedicated to student help requests. In order to encourage participation, roughly 7% of the course grade is assigned to unchecked classroom activities. I allow students to make up missed participation points until the end of the semester.
Expert Systems are one of the best methods which are typically employed in the assessment of application domains. Here, the expertise possessed by a human being in accomplishing specified tasks is enumerated as facts and rules at their knowledge bases , which commonly operates based on the data offered by users. In the specified knowledge, reasoning processes are carried out by means of heuristic methods in formulating solutions, . ES could be defined as enumerated in  as: “An intelligent computer program that uses knowledge
Covers fundamental concepts for intelligent systems that autonomously learn to perform a task and improve with experience, including problem formulations (e.g., selecting input features and outputs) and learning frameworks (e.g., supervised vs. unsupervised), standard models, methods, computational tools, algorithms and modern techniques, as well as methodologies to evaluate learning ability and to automatically select optimal models. Applications to areas such as computer vision (e.g., character and digit recognition), natural- language processing (e.g., spam filtering) and robotics (e.g., navigating complex environments) will motivate the coursework and material.
a better marginal accuracy than that fabricated from the CS3500 system. It can be assumed that the difference in the marginal accuracy between the systems is related to the software design of the restoration in compensation for the sintering shrinkage of zirconia in each system. Even though the zirconia restorations fabricated from both CAD-CAM Table 2 ANOVA for marginal accuracy of full-arch restorations at canine and molar abutments on medial and lateral sides for different fabrication techniques
data-path level depends on clock edge. When positive edge of clock input data transfer through upper data-path and when negative edge of clock input data transfer to lower data-path at any time input of ‘l3’ is zero then the output of ‘l3’ directly consider ‘Q’ is one. In this project we can proposed two methods but mthod2 is give the more accurate output compare to method (a).Thus the proposed Design has become more efficient in terms of area, power and speed which
Teaching digital systems and logic is a complex task faced by the university lecturers. In general the lecturers pass the subject knowledge use of by course materials and students’ notes, which are in a “lifeless” form. To get this task complete, the students visit the lecturers, make notes and have some tutorial tasks performed. The motivation to learn from such material or method may not be so high. Especially when teaching the concepts behind the digital systems, students should have the possibility of seeing the outcomes of the scenario based on the changes they make . Without visually seeing those, it will be hard for the undergraduate students to acquire the required knowledge on the subject.
With the explosive growth, the demand, and the popularity of portable electronic products, the designers are driven to strive for smaller silicon area, longer battery life, higher speed, and enhanced reliability is increases with technology scaling. As Technology scaling increases the transistor count and operating frequency, which push the market demand for more and more function in Integrated circuit. However scaling always increases leakage power dissipation. As channel length reduces which results in increase of power dissipation with respect to technology progresses. To reduce the power consumption different logicdesign techniques like CMOS complementary logic, Dynamic
The Paraconsistent Annotated Logics with annotation of two values (PAL2v) is a class of Paraconsistent Logics particularly represented through a Lattice of four vertices (see [1-4]). The main feature of Paraconsistent Logic is the ability to accept contradiction and with fundamental concepts of the PAL2v was created the Paraquantum Logic (P QL ) [5,6]. Through the paraquantum equations
CMOS, Pseudo NMOS, Dynamic CMOS, CMOS Domino logic, Cascade voltage switch logic (CVSL), Modified Domino logic, Pass Transistor Logic (PTL) have been proposed [1-3]. Power dissipation depend on device structure property like gate oxide thickness, channel length, doping profile etc. as they are due to different physical phenomena Although Static CMOS Logic has been the most popular design approach for the past three decades [4, 5]. By scaling down the feature size of MOSFET devices in nano-meter, the supply voltage should be scaled down to avoid hot- carrier effects in CMOS circuits. To enhance the speed of the CMOS circuits, threshold voltage of the circuits has to be scaled down.
Computer Aided Design (CAD) and Computer Aided Engineering (CAE) are two significantly different disciplines, and hence they require different shape models representations. As a result, models generated by CAD systems are often unsuitable for Finite Element Analysis (FEA) needs. In this paper, a new approach is proposed to reduce the gaps between CAD and CAE software's. It is based on new shape representation called mixed shape representation. The latter simultaneously supports the B-Rep (manifold and non-manifold) and polyhedral representation, and creates a robust link between the CAD model (B-Rep NURBS) and the polyhedral model. Both representations are maintained on the same topology support called the High Level Topology (HLT), which represents a common requirement for simulation model preparation. An innovative approach for the Finite element simulation model preparation based on the mixed representation is presented in this paper, thus a set of necessary tools is associated to the mixed shape representation. They help to reduce the time of model preparation process as much as possible and maintain the consistency between the CAD and simulation models.
