Summary

This project shows some selected signal techniques, including image and audio processing, using the Matlab digital signal processing and image processing toolboxes. The project is divided to 3 parts.Part I includes design and implementation of different types of filters for filtering signal that has different sinusoidal frequency components or noise. The comparison was made between FIR low pass flter, butterworth filter, Chebycheve Type I low pass filter and Chebycheve Type II low pass filter. Then different types of IIR Butterworth filters were designed and implemented to filter a signal that has many harmonics components, including low pass filter, high pass filter, stop band filter and band pass filter.Part II examined audio filtering in the sense of specific frequency suppression and extraction. There are many different types of filters available for the construction of filters. We will specifically use the Butterworth filter. An audio signal was read and different types of filters, including low pass filter, high pass filter, stop band filter and band pass filter, were designed and implemented in order to filter the audio signal from some frequency bands. Then the discrete cosine transform compression examined on the audio signal  at different compression rates: 50%, 75% , 87.5% Part III deals with image processing; the project shows examples in smoothing, sharpening, and edge detection. Other useful operations on the image were tested, including image cropping, image resizing, image, histogram equalization and altering image brightness

    'Eli linge libaluleke kakhulu kumzi ontsundu olahlekileyo. Xa sivuselela izinto zenkcubeko yethu esalahlekana nazo ngonoquku, mhla kwafika iintlanga zasemzini.' – Dr Loyiso Nqevu
    Returning to the family homestead in the Eastern Cape for the holidays, and worried that your city ways and less than perfect knowledge of Xhosa culture will get you a wagging finger in the face from ooMalume – the uncles?
    No need to fret. Don't Upset ooMalume! captures the essence of Xhosa heritage and culture, and explores different aspects of village life. It covers a range of topics, from major Xhosa life ceremonies and traditional clothing, to the significance of uronta (the rondavel) and ubuhlanti (the kraal). Not forgetting the importance of traditional food, the author describes popular dishes, edible forage and even medicinal plants.
    This book was born from writer and agriculturalist Hombakazki Mercy Nqandeka's concern that aspects of Xhosa heritage will be lost to future generations. By interweaving her guide to Xhosa culture with stories from her daily life at Mqele and Bulungula villages, and lessons taught to her by her mother and her late grandmothers, she hopes to help reconnect Xhosa people to their roots.
    Akukho nto imnandi ngathi kukungeqiwa ziindaba xa kuncokolwa ngesiXhosa esintsokothileyo nesineziqhulo. Bathi bezincokolela abantu abadala bexuba nakwintetho yokuhlonipha ube usiva yonke into abayithethayo. Oko kubonisa ukuzingca nokuzingomba isifuba ngolwimi lakho lesiXhosa.
    Le ncwadi yenzelwe abantu abasithandayo isiXhosa nabafuna ukufunda nzulu ngolwimi nenkcubeko yesiXhosa. Ungabadanisi ooMalume, lola isiXhosa sakho ngale ncwadi.

    The essential guide to differential diagnoses 
    Appreciation of the differential diagnosis for a particular symptom or sign has been a pillar of the practise of general medicine for generations of doctors. 
    Keeping a broad differential in mind when approaching the new patient is often key to avoid pitfalls of tunnel vision in management. Equally, the importance of the differential diagnosis in undergraduate and postgraduate examinations cannot be understated. 
    This book contains a series of lists of differential diagnoses for general medical presentations. We hope it will be of use for doctors wishing to refresh their memory with a quick reference guide, students of undergraduate medicine as well as postgraduate doctors in preparation for Membership of the Royal College of Physicians (MRCP) examinations. 
    The best way to navigate the book is to identify the symptom or clinical feature required using the contents pages but the lists can be read in sequence for general readers.
