Determining the identity of this " mystery ship " became of regional interest, resulting in daily front-page newspaper articles.

Determining the composition of the Memorial depends on the dates of Nehemiah's mission: It is commonly accepted that " Artaxerxes " was Artaxerxes I ( there were two later kings of the same name ), and that Nehemiah's first period in Jerusalem was therefore 445-433 BC ; allowing for his return to Susa and second journey to Jerusalem, the end of the 5th century BC is therefore the earliest possible date for the Memorial.

Determining the satisfiability of a formula in conjunctive normal form where each clause is limited to at most three literals is NP-complete ; this problem is called " 3SAT ", " 3CNFSAT ", or " 3-satisfiability ".

Determining the satisfiability of a formula in which each clause is limited to at most two literals is NL-complete ; this problem is called " 2SAT ".

Determining the satisfiability of a formula in which each clause is a Horn clause ( i. e. it contains at most one positive literal ) is P-complete ; this problem is called Horn-satisfiability.

Determining styles in capoeira is a very tough task, since there was never a unity in the original capoeira, or a teaching method before the decade of 1920.

Determining an instance of the membership problem ; i. e. given a string, determine whether where is the language generated by some grammar ; is also known as parsing.

Determining a " country of origin " is thus much more difficult than determining other aspects of a gem ( such as cut, clarity etc.

Determining the presence of both parts of this definition is not always straightforward, as hypoglycemic symptoms and effects are vague and can be produced by other conditions ; people with recurrently low glucose levels can lose their threshold symptoms so that severe neuroglycopenic impairment can occur without much warning, and many measurement methods ( especially glucose meters ) are imprecise at low levels.

Determining how many people died in these massacres overall is difficult.

Determining a precise value for a particular knot is difficult because many factors can affect a knot efficiency test: the type of fiber, the style of rope, the size of rope, whether it is wet or dry, how the knot is dressed before loading, how rapidly it is loaded, whether the knot is repeatedly loaded, and so on.

Determining whether a particular event or proceeding constitutes the commencement of adversarial criminal proceedings requires both an examination of the rules of criminal procedure for the jurisdiction in which the crime is charged and the Supreme Courts cases dealing with the issue of when formal prosecution begins.

Determining the distances to astronomical objects is crucial to understanding them, but the vast majority of objects are too far away for their distances to be directly determined.

Determining if the customer is likely to return to reclaim an item is a subjective decision, and wily customers may attempt to persuade the pawnshop owner that the item in question is important to them (" that necklace belonged to my grandmother, so I will certainly return for it "), and they will claim that they will return to recover it.

Determining a precise distance to the LMC, as with any other galaxy, was challenging due to the use of standard candles for calculating distances, with the primary problem being that many of the standard candles are not as ' standard ' as one would like ; in many cases, the age and / or metallicity of the standard candle plays a role in determining the intrinsic luminosity of the object.

Determining an appropriate and safe exercise program is challenging and must be carefully individualized to each person being sure to account for all contraindications and precautions.

Determining the date and length of Eric's reign ( before and after his father's death ) is a challenging and perhaps impossible task based on the confused chronology of our late sources.

Determining what records have enduring value can be challenging.

Determining how written text is spoken is a hugely challenging task in itself.

Determining that the section of the defensive line was manned primarily by artillery, he ordered an attack.

Determining the structure of LDL has been a tough task because of its heterogeneous structure.

Determining the number of films he made during the early part of his career is difficult because the ad copy rarely named him.

Determining a property or site location based upon Magnetic North will result in inaccuracies because true magnetic north fluctuates.

Determining whether news is " good " or " bad " must be determined by the price action of the stock, because the market reaction may not match the tone of the news itself.

The color, consistency, acidity, and other characteristics of the discharge may be predictive of the causative agent. Determining the agent is especially important because women may have more than one infection, or have symptoms that overlap those of another infection, which dictates different treatment processes to cure the infection.

Determining which amino acid forms the N-terminus of a peptide chain is useful for two reasons: to aid the ordering of individual peptide fragments ' sequences into a whole chain, and because the first round of Edman degradation is often contaminated by impurities and therefore does not give an accurate determination of the N-terminal amino acid.

Determining mass is even more difficult, because little evidence of soft tissues survives in the fossil record.

Determining the optimal parameters in a model of this type is not trivial, and local numerical optimization methods such as gradient descent can be sensitive to initialization because of the presence of local minima of the training criterion.
