In Broad Daylight by Ha Jin is a poignant and thought-provoking novel that explores the complex dynamics of power, corruption, and justice in a small Chinese village during the Cultural Revolution.

The story follows the lives of two main characters: Ning, a schoolteacher who becomes embroiled in a power struggle with the local party secretary, and Shuyu, Ning's wife, who is caught between her loyalty to her husband and her fear of the party's retribution. Through these characters, Ha Jin deftly illustrates the ways in which the Cultural Revolution's ideology of revolution and class struggle was used to justify violence and abuse of power, as well as the ways in which individuals were forced to navigate the treacherous waters of political loyalty and personal morality.

One of the key themes of the novel is the corrupting influence of power. The party secretary, Lao Li, is a ruthless and cunning man who will stop at nothing to maintain his position of authority, even if it means resorting to threats, intimidation, and violence. Ning, on the other hand, is a principled and honest man who refuses to bow to Lao Li's demands, even when it puts him and his family in danger. As the conflict between the two men escalates, it becomes clear that Lao Li's power is not derived from his leadership or moral character, but rather from his ability to manipulate the system and use fear and intimidation to silence his opponents.

Another theme that emerges in the novel is the role of justice in a society where the rule of law is subverted by those in power. Ning's struggle to bring Lao Li to justice is a poignant reminder of the importance of due process and the rule of law in upholding a just society. However, Ha Jin also highlights the ways in which the legal system can be used to protect the powerful and punish the weak, as Ning's efforts to seek justice are repeatedly thwarted by the corruption and bias of the local authorities.

Ultimately, In Broad Daylight is a powerful and poignant exploration of the ways in which power and corruption can corrupt even the most well-intentioned individuals. Ha Jin's vivid and nuanced portrayal of the characters and their struggles is a testament to his skill as a writer, and the novel serves as a thought-provoking and timely reminder of the dangers of unchecked power and the importance of upholding justice and the rule of law.

Another portable device that we designed monitors pressure sensors placed inthe shoes to determine the dynamic changes in pressure distribution under the footfor patients such as diabetics who have insensate feet Mehta et al. The PC itself has become a powerful tool inbiomedical computing applications. Medical diagnostic tools are prevalent using the support of medical signals. We can carry around a significant amount ofcomputing power wherever we go.

LabVIEW National Instruments is a visual computing language available onlyfor the Macintosh that is optimized for laboratory applications. The analysis of the signals can be used for the evaluation of the differently abled persons to predict the treatment outcomes. Such a computer, as itsdesigners envisioned, would have tremendous versatility because its function as aninstrument could be completely revised simply by changing the program stored inits memory. Such an instru-ment can be truly a personal computer looking for problems specific to a given pa-tient during the patients daily routines. Vats of salt water provided the electrical connection to thebody. The ones on which we con-centrate in this book are those that monitor and analyze physiological signals froma patient.

OTHER BIOMEDICAL SIGNAL PROCESSING AREAS: Gene detectors: these are the microprocessor chips which are often placed in the bodies of organisms, generally animals. As such, it can be concluded that the Biomedical Signal processing has been the key factor in the detection, research and analysis fields of the Biomedics. Park Ridge, NJ: Noyes Medical Publications,pp. Upper Saddle River, NJ: Prentice Hall, 1989. Forth is useful for real-time applications, but it is a nontraditional, stack-orientedlanguage so different from other programming languages that it takes some timefor a person to become a skilled programmer.

Onthe strength of its name alone, IBM standardized the personal desktop computer. Other high-level languages such as FORTRAN and Pascal plot near the diagonalindicating that they are good compromises in terms of the trade-off between pro-gram development time and run time per procedure but do not usually producecode with enough run-time speed for real-time signal processing applications. The two electrodes necessary to acquire an ECG togetherwith the electrolyte and the salt-filled torso act like a battery. These algorithmstypically include digital signal processing, which is the emphasis of this book,together with decision logic in order to analyze biomedical signals as well asmedical images. The C language, which is used to develop modern versions of the Unix operatingsystem, provides a significant improvement over assembly language for imple-menting most applications Kernighan and Ritchie, 1978. The company has predicted that they will be able to continueproducing microprocessors with this exponential growth in the number of transis-tors per microprocessor until at least the end of this century.

In the case of the ICU, there are normally several sensors connected to each pa-tient receiving intensive care, and the processor actually usually more than oneprocessor monitors and analyzes all of them. Chapter 7 covers a special class of integer coefficient filters that are particularlyuseful for real-time signal processing because these filters do not require floating-point operations. His research interests include neural signal processing, biomedical signal processing, and medical instrumentation. You could capture anECG directly from a patient and show the waveform on the graphics display. A predominant VCG researcher in the 1950s named Frank shaped a plaster castof a subjects body like the one shown in Figure 2. The C programming language.

Once the transfer coefficients are known, the forward problem of electrocardiog-raphy can be solved for any dipole source. Appendices A, B, and C provide details of interfacing and use of the two physi-cal signal conversion devices supported as well as the virtual signal conversiondevice that can be used on any PC. Speech Analysis Rabiner, L. It then convertsthis activity measurement to the equivalent number of calories and displays thecumulative result on an LCD display Doumas et al. Although it is a relatively fast compiled language, LabVIEW is not optimized forreal-time applications; its strengths lie particularly in the ability to acquire and pro-cess data in the laboratory environment.

This method causes no discomfort to a patient and is often used for diagnosing heart disorders such as coronary heart disease, pericarditis or inflammation of the membrane around the heart, cardiomyopathy or heart muscle disease arrhythmia and coronary thrombosis. Such a program is easy toimplement today on the modern PC using a high-level computing language such asPascal or C. We developed this book with its set of laboratories and special software to pro-vide a mechanism for anyone interested in biomedical signal processing to studythe field without requiring any other instrument except an IBM PC or compatible. These systems have made life easy and increased the life expectancy of people by decades. IEEE Frontiers of Eng. Another example is that when ultrasound travels though bile in a gallbladder it will echo back strongly if it hits a solid gallstone.
