Part A 1a. No diamonds are emeralds, diamonds is the subject and emeralds is the predicate, the terms are distributed because no S is P (E type proposition); it is a negative statement because of the quality of the subject. The quantity of the subject class is a particular proposition because no diamonds are emeralds. 1b. At least one person is a nerd, person is the subject and nerd is the predicate, the terms are distributed because one S exists so that S is a P (I type proposition); it is an affirmative statement because of the quantity of ...

It is an intersecting fact to not that to date the notion of dynamic networks refers to either one of two different concepts. First the pattern of Links, in a network topology evolves dynamically in time. Second the nodes can be individual dynamic systems coupled by static links [5, 6, 10, 22 24]. Adaptive networks are not new. Nearly all real world networks are to an extent adaptive and adaptive networks occurs in multiple disciplines today [12, 13, and 18]. What is new is that in recent years adaptive networks have become a focal point of extensive investigation using ...

Basic if statements are used to allow computers to take one of two courses of action and is an example of a branching or decision statement If else statements are used every day to allow us to make decisions and perform different activities as we compare the pros and cons of our decisions. In most cases, the process is automatic since we have performed the activity for so long we do not think of it as performing if else statements. An example of an everyday if else statement is with travel arrangements for example travelling by bus. In order ...

DeMorgan’s Theorem is one of the most important transformation rules in digital electronics. It is a pair of transformation rules which could be applied in propositional logic and are both valid for rules of inference. It was named after its developer Augustus De Morgan who is a British Mathematician. The simplest way to define DeMorgan’s Theorem is that the logical expressions remains unchanged when the inversion bar of the expression is broken and the operation is changed to its opposite. DeMorgan’s Theorem come about in order to simplify logical expressions in mathematics. It was influenced by ...

Introduction

The logistics management involves the supply chain management that is charged with the responsibility of planning, implementing and controlling the efficient forwarding and the reverse flow of goods and the storage of the goods. It involves all the processes that take place from the time a good or service is produced to the time it will be consumed by the consumers. These must all be done in order to meet the use requirements (Lichtenstein, 1996). There are several risks that are involved during the time a given commodity is being transported from the point of production to the time it will ...

How logic gates make electronic designs more efficient

Logic gates are used in electronics to implement a Boolean function. They produce a single logical output by performing a logical operation on logical inputs. Computer memory, registers and multiplexers constitute logic circuits. Diodes and transistors are used to implement logic gates. They serve the role of electronic switches. To improve the efficiency of electronic designs, logic gates are cascaded in a similar way as the composition of Boolean logic. They allow for the development of physical model of Boolean logic. The construction of logic gates using MOSFET makes it possible for use in circuit design to increase efficiency as well as the ...

Computer Architecture:

The Von Neumann Computer architecture and its importance: The Von Neumann computer architecture model was first described in a paper by Burks, John Von Neumann and Goldstein in 1946. The computer comprised a CPU, memory and I/O devices with a single set of buses connecting the CPU to memory. In this architecture, the program is stored in memory, and the processor fetches an instruction at a time from the memory and executes it. When the processor is reading data values from memory, it is unable to fetch the next execution instruction till data reading is complete. This situation where data and program ...

Introduction Considerable research attention has been given to the problems that mentally ill individuals face in getting and keeping jobs. See, for example, Cook et al. (2007) and Gilbride et al, 2003. Little research, on the other hand, concerns outcomes for such individuals once they are employed. Job stress can affect any job holder. Does a history of mental illness or a current condition exacerbate the stress? Are individuals with a background of mental illness more vulnerable to job stress than colleagues without such a background? These are important questions for those of us who are part of the population with a history ...

Introduction

Ultrasound can be defined as the use of high frequency sound waves (having a frequency above the range, which is audible to the normal human ear, i. e. varying between 20 Hz to 20,000 Hz) for changing the chemical properties of a substance (Ter Haar, 1999). Besides medical imaging, nowadays ultrasound has become an important therapy for the management of several orthopaedic clinical conditions (Ter Haar, 1999). Stimulation of the tissues beneath the skin’s surface using high frequency sound waves is likely to result in several therapeutic benefits. Tennis elbow (TE) or lateral humeral epicondylitis can be considered ...

In the world we live in today we are constantly bombarded with news that we are destroying our world. Organisations are clamouring for people to go green and try to do their bit to save mother earth or so we don’t lose her forever. People are still divided on what to believe or even what little contribution they may be able to do to make a difference in their world. Many people feel like they are just one person and are therefore too small to make any kind of change. However I know that if everybody had that same ...

Introduction (Summary)

A society is a connected group of individuals enabled by a long evolutionary process that enables them to acquire the skills necessary to survive in a tight social structure. It is difficult, but possible, to capture the structure of society in a model and apply the same model to navigate different problems and achieve objectives. While humans have become socially competent after many years of evolution, artificially intelligent systems need an explicit way in which they can represent, make and justify their decisions. Several approaches have been suggested over time through research. In robotics, models have been applied with the goal of capturing ...

Output X if between 0-50 OR 51-100 - Boolean variables are numerical variables with a single binary digit used to hold integer value 0 or 1.True is represented by 1 and false is represented by 0 - Conditions - ConditionA and ConditionB. It means that the output variables have condition A and ...

The Von Neumann architecture

The Von Neumann architecture can be described as a model of design for a digital computer which has a stored program. The main characteristic of the model is that there is only one storage structure which is the memory that holds both the data and the program. Some components of the model include the Memory, which holds both the data to be processed and data concerning the program processing the data. This memory is the Random Access Memory in modern computers. The control unit manages the process of moving both the data to be processed and the program processing the ...

Corse title:

1. Using Boolean algebra laws, a negation is denoted by a NOT gate in the circuit. Assume the input signal at X is 1. As it passes the NOT gate it becomes 0. Using Boolean algebra, note that NOT gate is a negation of the input signal, which is 1, hence the output becomes 0. This 0 is the input of the OR gate. This similar to the Y but, at Z the signal is not affected since there is no negation by NOT gate. The truth table for OR is a mathematical representation of Boolean algebra on logics is similar to ...

Introduction

The present problem is that nutrition and hydration are not considered priority nursing interventions and are performed in a suboptimal manner as shown in many studies (Begum & Johnson 2010; Godfrey et al 2012; Ross et al. 2011). Food and feeding times are institutionalized and fail to consider the preferences of the patient and other needs that may be linked with dining. In order to learn the most appropriate interventions in providing patients with nutrition and hydration, there is a need to perform a literature search and determine whether this topic has already been extensively studied or if further research is needed. The ...

Assembly language is a programming language that communicates directly to the computer hardware. High level programming languages have a one-much instruction relationship with assembly language. This means one instruction may expand into several machine or assembly instructions. Machine language deals with programming of microprocessors that are compatible with Intel IA-32 and AMD×86 processors that operate using Microsoft Windows. There has been a development in the processors from the Intel Pentiums through to the AMDs (Advanced Micro Devices).

Assembly languages such as Microsoft Macro Assembler (MASM) and Turbo Assembler (TASM) are used for programming. An assembler converts source code programs from assembly ...
