2. Define USABILITY as the standard set by ISO (9241-11) and discuss the key properties or specifications contained in the definition with pragmatic scenarios 3. Identify any four (4) factors that can be used to quantify software userfriendliness for usability testing. 4. Evaluation is concerned with gathering data about the usability of a design or product by a specified group of users for a particular activity within a specified environment or work context. As an evaluation expert, discuss four evaluation approaches you will recommend for analysis throughout the design processes and under what favorable scenario can each approaches be executed. 5. In HCI, usability requires project management and careful attention to requirements analysis and testing for clearly defined objectives. Discuss four (4) major reasons why requirements analysis needs careful attention. Read More »

There are two conditions for calling a domain atomic. Mention them and cite one example in [05] this regard EXPERT ANSWER Solution Step :- 1 The two conditions for calling a domain atomic are that the domain must be irreducible and that it must be a maximal consistent subset of the Herbrand interpretation. An example …

EXPERT ANSWER

Precipitated protein is centrifuged to a total moisture content of 28 wt%. It is then dried in a batch drier for 6 hours under constant drying conditions to 16 wt% (total moisture). The critical moisture content for the solids is 11 wt% (total moisture). The equilibrium moisture content is 4 kg H2O/100 kg dry solid. …

Precipitated protein is centrifuged to a total moisture content of 28 wt%. It is then dried in a batch drier for 6 hours under constant drying conditions to 16 wt% (total moisture). The critical moisture content for the solids is 11 wt% (total moisture). The equilibrium moisture content is 4 kg H2O/100 kg dry solid. How long would it take to dry a sample of the same size from a free moisture content of 25 wt% to 4 wt% under the same drying conditions? All given moisture contents are in dry basis. Assume that the drying rate (in the falling rate period) is a linear function through the origin Read More »

If 1 m3 of air at a pressure of 1 atm is mixed with 0.1 m3 of carbon dioxide at 1.5 atm and the mixture is compressed so that its total volume is 1 m3, estimate the concentration of carbon dioxide in the mixture in (a) w/w, (b) w (kg)/V(m3), and (c) mole fraction at …

If 1 m3 of air at a pressure of 1 atm is mixed with 0.1 m3 of carbon dioxide at 1.5 atm and the mixture is compressed so that its total volume is 1 m3, estimate the concentration of carbon dioxide in the mixture in (a) w/w, (b) w (kg)/V(m3), and (c) mole fraction at a temperature of 25°C. Mean molecular weight of air is 28.8 g/mol, and of carbon dioxide 44 g/mol. ((a) 18.6%, (b) 27%, (c) 0.13) Read More »
