What is the concept of creating safer and more efficient equipment called?
prudent avoidance, ergonomics, product design, workplace design
The avoidance of personal prejudice or bias is an important trait of a scientist true or false?
This is true because if any bias is present, the outcome may be affected by the scientist's method.
What are the disadvantages to using aversive control?
There are many drawbacks of aversive control. 1.) Anger and Fear are side effects: The greatest lesson the victim of punishment may learn is to hate the punisher 2.) The whole situation may lead to total avoidance. For example, a child who is severely punished for breaking a family rule may run away from home. 3.) What appears to be a punishment may actually be a reinforcement. For instance, a student who is publicly scolded in class may enjoy the attention. 4.) Punishment may encourage peer glorification of the sufferer. The "martyr's behavior may be imitated.
What are the science processes and their meaning?
. Observing2. Classifying3. Inferring4. Predicting5. Measuring6. Communicating7. Using Space/Time Relations8. Defining Operationally9. Formulating Hypotheses10. Experimenting11. Recognizing Variables12. Interpreting Data13. Formulating ModelsThe first of the science process skills, observation, involves noting the attributes of objects and situations through the use of the senses. Classification goes one step further by grouping together objects or situations based on shared attributes. Measurement involves expressing physical characteristics in quantitative ways. Communication brings the first three skills together to report to others what has been found by experimentation.Inference and prediction are the more sophisticated of the science process skills. Beyond simply seeing and reporting results, scientists must extract meaning from them. These skills can involve finding patterns in the results of a series of experiments, and using experience to form new hypotheses. It is also essential for a scientist to be able to distinguish his objective observations from his inferences and predictions. This is because scientific inquiry and study depend on objectivity and an avoidance of hasty assumptions in experimentation.All of the science process skills contribute to a larger purpose, namely problem solving. Problem solving is the reason for scientific inquiry, and forms the essence of it. A typical experiment wherein a scientist uses process skills and the scientific method will start with certain questions being asked. Based on prior knowledge and experience, the scientist will make an educated guess as to the answer or outcome. This hypothesis will guide the design and execution of an experiment.

What is difference between in deadlock prevention and deadlock avoidance and?
Deadlock PreventionDifference from avoidance is that here, the system itself is build in such a way that there are no deadlocks.Make sure atleast one of the 4 deadlock conditions is never satisfied.Deadlock AvoidanceAvoid actions that may lead to a deadlock.Think of it as a state machine moving from 1 state to another as each instruction is executed. moreoverDeadlock detection is a technique to handle deadlocks which tries to find out if the system is in deadlock and then works to recover it from the deadlock if any exists. It is used as an afterthought and is not coordinated with the resource allocating procedures.Deadlock avoidance is a technique which works hand-in-hand with the resource allocation and tries to ensure that a resource request made in a non-deadlocked state is granted only if it will not lead to a deadlock in the future. This technique however makes unrealistic demands about the kind of information it needs from process, in that, it requires the entire pattern of resource requests, past & future.
What is the difference among deadlock avoidance detection and prevention?
Deadlock avoidance involves ensuring that the system never enters a deadlock state by using techniques like resource allocation strategies (e.g., Banker's algorithm) to ensure that resources are allocated in a way that avoids deadlock. Deadlock detection, on the other hand, involves periodically checking the system to see if a deadlock has occurred after it has happened. Deadlock prevention focuses on designing algorithms and protocols in a way that eliminates one of the conditions necessary for deadlock to occur, such as by ensuring that resources are requested in a specific order.
What are the differences between deadlock avoidance and deadlock prevention in operating systems?
Deadlock Prevention: o Preventing deadlocks by constraining how requests for resources can be made in the system and how they are handled (system design). o The goal is to ensure that at least one of the necessary conditions for deadlock can never hold. * Deadlock Avoidance: o The system dynamically considers every request and decides whether it is safe to grant it at this point, o The system requires additional apriori information regarding the overall potential use of each resource for each process. o Allows more concurrency. Similar to the difference between a traffic light and a police officer directing traffic. * Deadlock deduction:- Often, neither avoidance nor deadlock prevention may be used. Instead deadlock detection and process restart are used by employing an algorithm that tracks resource allocation and process states, and rolls back and restarts one or more of the processes in order to remove the deadlock. Detecting a deadlock that has already occurred is easily possible since the resources that each process has locked and/or currently requested are known to the resource scheduler or OS. Detecting the possibility of a deadlock before it occurs is much more difficult and is, in fact, generally undecidable, because the halting problem can be rephrased as a deadlock scenario. However, in specific environments, using specific means of locking resources, deadlock detection may be decidable. In the general case, it is not possible to distinguish between algorithms that are merely waiting for a very unlikely set of circumstances to occur and algorithms that will never finish because of deadlock. Deadlock detection techniques include, but is not limited to, Model checking. This approach constructs a Finite State-model on which it performs a progress analysis and finds all possible terminal sets in the model. These then each represent a deadlock.

What are the various strategies are used to handle deadlock and what is centralized and distributed deadlock detection and prevention?
There are four strategies of dealing with deadlock problem:1. The Ostrich ApproachJust ignore the deadlock problem altogether.2. Deadlock Detection and RecoveryDetect deadlock and, when it occurs, take steps to recover.3. Deadlock AvoidanceAvoid deadlock by careful resource scheduling.4. Deadlock PreventionPrevent deadlock by resource scheduling so as to negate at least one of the four conditions.
