Computer Science - BSc (Hons)

This module builds on the foundation of object-oriented design and implementation found in module CO320 Introduction to Object-Oriented Programming to provide a deeper understanding of and facility with object-oriented program design and implementation. More advanced features of object-orientation, such as inheritance, abstract classes, nested classes, graphical-user interfaces (GUIs), exceptions, input-output are covered. These allow an application-level view of design and implementation to be explored. Throughout the module the quality of application design and the need for a professional approach to software development is emphasized.

This module provides an introduction to object-oriented software development. Software pervades many aspects of most professional fields and sciences, and an understanding of the development of software applications is useful as a basis for many disciplines. This module covers the development of simple software systems. Students will gain an understanding of the software development process, and learn to design and implement applications in a popular object-oriented programming language. Fundamentals of classes and objects are introduced, and key features of class descriptions: constructors, methods and fields. Method implementation through assignment, selection control structures, iterative control structures and other statements is introduced. Collection objects are also covered and the availability of library classes as building blocks. Throughout the course, the quality of class design and the need for a professional approach to software development is emphasized

This module will introduce students to fundamental concepts of functional and concurrent programming, using a suitable language (e.g. Erlang) as a vehicle to put these concepts into practice. The first part of the module will cover basic ideas in functional programming, such as expressions, types, values, lists, pattern-matching and recursion, together with the specific language concurrency model, including process creation, message sending and receiving. Good concurrent design practices will be considered, based on networks of communicating processes (e.g. Actor and CSP models), and avoiding problems such as deadlock, livelock and starvation.

The later part of the module will cover more advanced topics (higher-order functions) and look at alternative concurrency models (e.g. synchronous, channel-based, join-based and shared-memory) and their relationship to the model described in the first part of the module. Alongside this, consideration will be given to the relevance and applicability of functional and concurrent programming for use in real applications.

Students taking this module will undertake two or (typically) more assignments for the Kent IT Clinic (KITC). Each assignment will be of one of three types: .

Work on one of KITC’s contracts with an external client. To the extent that client-funded workallows, every student will be given at least one assignment of this type. Wherever practical, astudent will be encouraged to participate in the negotiation and pricing of contracts, under theultimate supervision of KITC management. For each assignment, the student may work on theassignment individually or as part of a group, as directed by KITC.

A contribution to the infrastructure of KITC itself. These assignments work in a similar way to external assignments, but with KITC as the client.

Formulating a costed proposal for the future development of KITC, and presenting reasoned argument in support of the proposal to KITC management, as a candidate for inclusion in KITC’s strategic plan for the following academic year. Every student will have at least one assignment of this type.

The project gives you the opportunity to follow and develop your particular technical interests, undertake a larger and less tightly specified piece of work than you have before (at university), and develop the project organisation, implementation and documentation techniques which you have learnt in other modules. The technical and professional aspects of project courses are seen as particularly important by both employers (who will often bring them up in interviews) and by professional bodies.

The project may be self-proposed or may be selected from a list of project proposals. Typically, a project will involve the specification, design, implementation, documentation and demonstration of a technical artefact. The project is supervised by a member of the academic staff, who holds weekly meetings with the group, during which s/he will give general advice and will assess the progress of the group and the contributions by individual students.

Project deliverables are:

- a technical report, in the style of an academic paper, describing the scientific/technical outcome of the project;

- a well-indexed corpus of material that supports the achievements claimed.

In addition, each individual prepares a report outlining his/her contributions to each of the various aspects of the project. This report should not be a repeat of other material delivered as part of the project, but an assessment of the progress of the project and reflections on what the individual has learnt from undertaking it. In particular, it should include a description of the particular activities and outcomes that individual has contributed to the project, and of how the group worked together. This report will be discussed at a viva voce examination which should include a short presentation/demonstration of the project.

Students will spend one half-day per week for ten weeks in a school with a nominated teacher. They will observe sessions taught by their designated teacher and possibly other teachers. Later they will act somewhat in the role of a teaching assistant, by helping individual pupils who are having difficulties or by working with small groups. They may take ‘hotspots’: brief sessions with the whole class where they explain a technical topic or talk about aspects of university life. They must keep a weekly log of their activities. Each student must also devise a special project in consultation with the teacher and with the module convener. They must then implement and evaluate the project.

This module is designed to provide students across the university with access to knowledge, skill development and training in the field of entrepreneurship with a special emphasis on developing a business plan in order to exploit identified opportunities. Hence, the module will be of value for students who aspire to establishing their own business and/or introducing innovation through new product, service, process, project or business development in an established organisation. The module complements students' final year projects in Computing, Law, Biosciences, Electronics, Multimedia, and Drama etc.

The curriculum is based on the business model canvas and lean start up principles (Osterwalder and Pigneur 2010) on designing a business plan for starting a new venture or introducing innovation in an established organisation.

The module will cover a mixture of theoretical and practical topics in the area of the Internet of Things (IoT), that is, the use of Internet technologies to access and interact with objects in the physical world. This will include coverage of the range of sensor and actuator devices available, ways in which they communicate and compute, methods for getting information to and from IoT-enabled devices, and ways of visualising and processing data gained from the IoT. A practical component will consist of building the hardware and software for a sensor network and a system to visualise data from that network.

A study of techniques for interpreting and compiling programming languages, implementing them in a typed functional programming language (e.g., OCaml, Haskell). The module will outline a whole compiler from source to machine code, but will focus in depth on key algorithms and techniques. Possible in-depth topics include:

• writing interpreters,

• Hindley-Milner type inference,

• register allocation,

• garbage collection,

• abstract interpretation,

• static single assignment form.

The implemented language will be based on a simple imperative (e.g., Pascal-like) language with some extensions to address advanced topics in data layout (e.g., closures, objects, pattern matching). The course will be organized around a simple, but complete, example compiler that the student will have to understand and modify.

The module aim is to give students an overview and understanding of key

theoretical, practical and philosophical research and issues around

computational creativity, and to give them practical experience in writing and

evaluating creative software.

This module shows students what trade-offs are involved in designing a programming language, and how those trade-offs ultimately influence programmer productivity. The module starts with a quick, example-based introduction to the basics of programming languages. It then continues with a series of problems that are each solved in several programming languages. After each problem, we stop and reflect on which language features help and which hinder. Finally, towards the end of the module, several of the language features previously identified are discussed in a more general setting. Indicative examples are:

* Basics of programming languages, such as: C++, C#, Dart, Go, Haskell, Java, Javascript, MATLAB, OCaml, Pyret, Python, Scala, Swift, R, Racket, Rust.

* Problem solving, in multiple languages. The problems will involve concepts such as parsing, evaluation, trees, graphs, memorization, randomization, big data algorithms, reactive user interfaces.

* Language features: pattern matching, first order functions, polymorphism, effects, exceptions, types, algebraic data types, modules, objects, classes.

This module explores a range of different data mining and knowledge discovery techniques and algorithms. You learn about the strengths and weaknesses of different techniques and how to choose the most appropriate for any particular task. You use a data mining tool, and learn to evaluate the quality of discovered knowledge.

The module introduces fundamental techniques employed in image processing and pattern recognition providing an understanding of how practical pattern recognition systems may be developed able to address the inherent difficulties present in real world situations. The material is augmented with a study of biometric and security applications looking at the specific techniques employed to recognise biometric samples.

This module introduces the theory and practice of employing computers as the control and organisational centre of an electronic or mechanical system, and examines issues related to time critical systems. It also provides exposure to practical embedded systems design through practical work, with one assignment exploring the ideas of real-time operating systems introduced in the lectures and a second using a microcomputer programmed in 'C' to control the ignition timing of a simulated petrol engine.

The module will study some of the major works in the history of modern philosophy of cognitive science and artificial intelligence. An indicative list of topics is: The Turing test; the Chinese Room argument; the frame problem; connectionism; extended and embodied cognition; artificial consciousness. The approach will be philosophical and critical, and will involve the close reading of texts. Students will be expected to engage critically with the works being studied and to formulate and argue for their own views on the issues covered.

This module covers the basic principles of machine learning and the kinds of problems that can be solved by such techniques. You learn about the philosophy of AI, how knowledge is represented and algorithms to search state spaces. The module also provides an introduction to both machine learning and biologically inspired computation.
